Incenter of A Triangle The incenter is the one point in the triangle whose distances to the sides are equal. (See picture) 1  If the triangle is obtuse, such as the one on pictured below on the left, then the incenter is located in the triangle's interior.  If the triangle is acute, then the incenter is also located in the triangle's interior.

orthocenter 1 (geometry) : the intersection of the three lines that can be drawn flowing from the three corners of a triangle to a point along the opposite side where each line intersects that side at a 90 degree angle; in an acute triangle, it is inside the triangle; in an obtuse triangle, it is outside the triangle.

Orthocenter In a right-angled triangle, the orthocenter lies Choices: A. at the vertex containing the right angle B. outside the triangle C. at the midpoint of the hypotenuse D. inside the triangle Correct Answer: A Solution: Step 1: Step 2: Orthocenter is the point of intersection of the altitudes. Each leg in a right triangle forms an altitude. Step 3: So, in a right-angled triangle, the orthocenter lies at the vertex containing the right angle.

- Math Open Reference. This page shows how to construct (draw) the incenter of a triangle with compass and straightedge or ruler. The Incenter of a triangle is the point where all three angle bisectors always intersect, and is the center of the triangle's incircle. See Constructing the incircle of a triangle. In this construction, we only use two bisectors, as this is sufficient to define the point where they intersect, and we bisect the angles using the method described in Bisecting an Angle. The point where the bisectors cross is the incenter. The above animation is available as a printable step-by-step instruction sheet, which can be used for making handouts or when a computer is not available. The image below is the final drawing from the above animation. List of printable constructions worksheets.

Triangle Points of Concurrency A special segment of a triangle that divides an angle of the triangle into two equal angles. Altitude. In a triangle the perpendicular segment from a vertex of a triangle to the opposite side or the line that contains the opposite side. Point of Concurrency that is equal distant from the sides of the triangle.

- It is also the center of the triangle's incircle. The coordinates of the incenter are the weighted average of the coordinates of the vertices, where the weights are the lengths of the corresponding sides. The formula first requires you calculate the three side lengths of the triangle.

Incenter Back to Top. Given below are the steps to find the incenter of a triangle: 1. Draw a triangle of any dimension. 2. Using a compass, draw two arcs on two successive sides of the triangle from a vertex. There are no defined width for the arcs. 3.

Altitude of a triangle One of a triangle's points of concurrency. Try this Drag the orange dots on any vertex to reshape the triangle. Notice the location of the orthocenter. The altitude of a triangle (in the sense it used here) is a line which passes through a vertex of the triangle and is perpendicular to the opposite side. There are therefore three altitudes possible, one from each vertex.

Triangle The altitude of a triangle is the perpendicular from the base to the opposite vertex. (The base may need to be extended). Since there are three possible bases, there are also three possible altitudes. The three altitudes intersect at a single point, called the orthocenter of the triangle.

Triangle Points of Concurrency The medians of a triangle intersect at the centroid which is 2/3 the distance from each vertex to the opposite sides midpoint. Point of Concurrency that is the midpoint of the hypotenuse of a right triangle. Circumcenter. Point of Concurrency that is the vertex of the right angle in a right triangle.

How to Find the Incenter, Circumcenter, and Orthocenter of a Triangle Circumcenter: Where the three perpendicular bisectors of the sides of a triangle intersect (a perpendicular bisector is a line that forms a 90° angle with a segment and cuts the segment in half); the circumcenter is the center of a circle circumscribed about (drawn around) the triangle.

Orthocenter, Centroid, Circumcenter and Incenter of a Triangle Orthocenter. The orthocenter is the point of intersection of the three heights of a triangle. A height is each of the perpendicular lines drawn from one vertex to the opposite side (or its extension). Centroid

Incenter 1 The biggest circle that can be drawn inside a triangle is the incircle. The incircle will touch all sides of the triangle. The radius of the circle is the length of the perpendicular line drawn from the Incenter to any side.  For an equilateral triangle, incentre, circumcentre and centroid will all be the same.

Triangles A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle. We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60°.

Orthocenter of A Triangle If the triangle is obtuse, such as the one on pictured below on the left, then the orthocenter will be exterior to the triangle. If the triangle is acute, then the orthocenter is located in the triangle's interior

Centroid of a Triangle Centroid of a Triangle. A centroid of a triangle is the point where the three medians of the triangle meet. A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle. The centroid is also called the center of gravity of the triangle. If you have a triangle plate, try to balance the plate on your finger. Once you have found the point where it will balance, that is the centroid of that triangle. The centroid of triangle ABC.

- The orthocenter of a triangle is the intersection of the three altitudes of a triangle. Remember, the altitude of a triangle is a perpendicular segment from the vertex of the triangle to the opposite side. For example, for the given triangle below, we can construct the orthocenter (labeled as the letter H) using Geometers Sketchpad (GSP):
