How are the three angles related? Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.

Three angles of a triangle always add up to how many degrees? All triangles have a total of 180 degrees. The internal angles of any triangle add up to 180 degrees. Therefore, a RIGHT triangle's angle's added together equal 180 degrees. The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = 180 degrees. All triangles have a total of 180 degrees.

How Many Angles Does a Triangle Have? Like if angle A = 40 0, angle B = 60 0 then we can find third angle C as shown below: A + B + C = 180, Therefore angle C is equals to 80 0. So From above discussion we can say that there are total of three angles in a triangle, whose sum is equals to 180 0.

- 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.

There are angles on the outside, too! One equation might tell us the sum of the angles of the triangle. For example, x + y + z = 180. We know this is true, because the sum of the angles inside a triangle is always 180 degrees. What is w? We don't know yet. But, we may observe that the measure of angle w plus the measure of angle z = 180 degrees, because they are a pair of supplementary angles.

Math Terms. If any angle becomes 90 degrees or more, it is not an acute triangle. In any triangle, two of the interior angles are always acute (less than 90 degrees) , so there are three possibilities for the third angle: 1  Less than 90° - all three angles are acute and so the triangle is acute. 2  Exactly 90° - it is a right triangle. 3  Greater than 90° (obtuse): the triangle is an obtuse triangle.

Degrees: Circles, Triangles, Rectangles, Squares A triangle is a closed figure that has three sides and three angles. The sum of the three angles of every triangle always equals 180° . A right triangle always has one angle equal to 90° and two angles whose sum is 90° , making a total of 180° . Rectangles. A rectangle is a four sided shape with four right angles (90° ). The sides across from each other are always the same length and always parallel to each other. The four angles add up to a total of 360° .

Triangles In an equiangular triangle, all the angles are equal—each one measures 60 degrees. An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angle—an angle of 90 degrees. A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angle—it is more than 90 degrees. An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right angles—each one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.

- Since those triangles together cover 360 degrees, each triangle obviously covers 36 degrees of that total, so each triangle has one 36 degree angle. The interior angles of a triangle always add up to 180 degrees, and the other two angles are equal, so each of them is (180-36)/2 = 72 degrees. The angle between each pair of sides is two of those, or 144 degrees. Views · View Upvotes.

- A Right Angle Triangle contains one right angle. A right angle has a magnitude of 90°, or in radians (pi/2). A triangle has three angles forming the closed shape, the additi … on of which gives an angle of 180°, or pi radians. With two right angles, the addition of these alone gives 180° (pi radians), and therefore the last angle has a null value.

What makes a triangle a right triangle? Rating Newest Oldest. Best Answer: One of the angles is 90 degrees. The other two angles of course add up to 90 degrees. To show that a triangle is right angled the converse of the theorem of Pythagoras can be used. That is, if we square the longest side and it is found to equal the sum of the squares of the other two sides, we conclude the triangle is right angled. Source(s): mathboy · 6 years ago. Thumbs up.

Measuring the Angles of Triangles: 180 Degrees Finding a Missing Angle. Because all triangles add up to 180 degrees, we can use this fact to our advantage. Sometimes we will have a triangle for which we know the measurement of two of the angles. The unknown third angle is easy to find since we know that all of them added up will equal 180.

Can a triangle have only 1 acute angle? Sure - a triangle could have 40, 70 and 70 degree angles. There's probably an infinite more amount of those. not possible,for a triangle the sum of three angles should be 180 degree. so even one side has 0.1 degree the other can only have 90 degree and 89.9 degree.so it is not possible.
