How can u draw a traingle with 2 acute exterior angles? 88 is not more that 90, so the exterior angle would NOT be acute it would be OBTUSE. ALL TRIAGLES MUST HAVE 2 ACUTE INTERIOR ANGLES, other wise it iS NOT a traingle! there is no way, your teacher is either lying to you, stupid, or he has no idea what he is talking about, or is on crack.8 is not more that 90, so the exterior angle would NOT be acute it would be OBTUSE.

- There may be either 2 or 3. If there are only 2, the third angle is equal to or greater than 90 degrees. (the sum of the three angles must equal 180 degrees) If there are 3, … the triangle is called an acute triangle. 3 people found this useful.

- For any triangle it is universal truth that addition of all three angles will be one eighty degree (1800). Mathematically, it can be expressed as: ∠p + ∠q + ∠r = 180°, If we are given two angles out of three then substituting these values, one angle can be calculated using above formula.

Right Triangle Angle And Side Calculator No two angles can total to 180 degrees or more. Angle C is always 90 degrees; angle 3 is either angle B or angle A, whichever is NOT entered. Angle 3 and Angle C fields are NOT user modifiable. Again, this right triangle calculator works when you fill in 2 fields in the triangle angles, or the triangle sides. Angle C and angle 3 cannot be entered.

Remote, Exterior and Interior Angles of A Triangle Formula for Remote Interior Angles and Exterior Angles. As the picture below shows, an exterior angle (A) equals the sum of the remote interior angles. To rephrase it, the angle 'outside the triangle' (exterior angle A) equals D + C (the sum of the remote interior angles). The interactive program below allows you to drag the points of the triangle around.

- The exterior angle of a polygon and its corresponding interior angle always add up to 180° (because they make a straight line). For any polygon, the sum of its exterior angles is 360°. You can see this because if you imagine 'walking' all the way round the outside of a polygon you make one full turn.

Why Does a Triangle Have 180 Degrees? Now take a look at the two angles that make up the exterior angle for that corner of the triangle (the ones labeled “B” and “C”). As we know, if we add up the interior and exterior angles of one corner of a triangle, we always get 1800. And our little drawing shows that the exterior angle in question is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the angle in the bottom right corner to make a 1800 angle. For the sake of simplicity, we’ve made our drawing using a right triangle.

Right Triangle Trigonometry The right triangle below has an acute angle of 35º and a side of length 7. To find the measure of the other acute angle, just subtract the measures of the other two angles from 180º: To find the lengths of the other two sides, use trigonometric functions relating the given angle measure to the given side length.

- A triangle must be either acute, right, or obtuse. It also has three interior angles that always total 180 degrees. Because a right triangle has a right angle (exactly 90 degrees), the sum of its two remaining angles must be 90 degrees. These two angles are therefore inferred to be acute. The same holds true for an obtuse triangle, since it has an obtuse angle (measuring more than 90 degrees) that makes the sum of its two other angles be less than 90 degrees.

What's the sum of the exterior angles of a convex hexagon? Exterior angles are those that are formed by the difference between a straight line (180º) and an interior angle. We know that all interior angles on a convex hexagon add up to 720º, so on a regular convex hexagon, each interior angle would be 120º, because we divided 720º by 6 vertices. Now, we have to subtract 120º from 180º, and we get 60º, which is the measure of only one the exterior angle of a regular convex hexagon. Now, let's multiply 60º by 6 angles, and we get 360º, so the sum of all the exterior angles of a convex hexagon is 360º.

- Since angle A, from the triangle, and angles 1 and 2 form a straight (dotted) line, the sum of their measures is 180º. We also know that since the dotted line is parallel to BC that by alternate interior angles. This gives us: Substituting for angles 1 and 2 we have This result is true for all triangles: Summarizing:

Triangle Calculator The interior angles of a triangle always add up to 180°. Because of this, only one of the angles can be 90° or more. In a right triangle, since one angle is always 90°, the other two must always add up to 90°. A triangle is simply a polygon that has 3 sides.

- In the diagram shown above, we see triangle ABC and the dotted line through A that is parallel to BC. Since angle A, from the triangle, and angles 1 and 2 form a straight (dotted) line, the sum of their measures is 180º. We also know that since the dotted line is parallel to BC that by alternate interior angles. This gives us: Substituting for angles 1 and 2 we have This result is true for all triangles: Summarizing: Theorem: The sum of the three angles in a triangle is always 180º. Let's Practice: If two of the three angles in a triangle have measure 34º and 72º, what is the measure of the third angle? We have 34º + 72º = 106º. Therefore the third angle has a measure of 180º - 106º = 74º . In a triangle ABC, we have .

How can u draw a traingle with 2 acute exterior angles? Relevance. Rating Newest Oldest. Best Answer: it is not possible. all angles in a triangle add up to 180 degrees. if you have a triagle with ONE acute Exterior angle, that means that the interior angle would be 91 degress or more.8 is not more that 90, so the exterior angle would NOT be acute it would be OBTUSE. ALL TRIAGLES MUST HAVE 2 ACUTE INTERIOR ANGLES, other wise it iS NOT a traingle! there is no way, your teacher is either lying to you, stupid, or he has no idea what he is talking about, or is on crack.

Remote, Exterior and Interior Angles of A Triangle The Exterior, Interior and Remote Interior Angles. An exterior angle of a triangle, or any polygon, is formed by extending one of the sides of the triangle (or polygon). In a triangle, each exterior angle has two remote interior angles (see picture below). The remote interior angles are just the two angles that are inside the triangle and opposite from the exterior angle.

What is the measure of an exterior angle in a regular hexagon? If we look at the relationship between one interior angle of a polygon and the exterior angle at that vertex, we see that together they make a straight angle, 180 degrees. Therefore, if we know the measure of an interior angle, we can find the measure of its adjacent exterior angle by subtracting from 180 degrees. For example, in an equilateral triangle, the exterior angle is 360 divided by 3 angles = 120 degrees. So each interior angle is 180 - 120 = 60 degrees.
