WebAn angle bisector is a line that cuts an angle made by two adjoining lines equally. This means that the angle is made by two joining lines or made up of three points A, B, and C, with the angle between line AB and line BC, cut in half by an angle bisector DB, where C is a point in the graph. 00:00. 00:00.

Angle Bisector Theorem: Definition & Theorems of Triangle

WebThe triangle ABC is an isosceles triangle, therefore, AB=AC. Now the side AD is common in both the triangles ∆ADB and ∆ADC. As the line segment AD is the angle bisector of the angle A then it divides the line segment BC into two equal parts BD and CD. Therefore, BD =CD and AB = AC. Now according to the SSS postulate, the two triangles are ... WebMar 1, 2024 · The incenter theorem shows that the angle bisectors dividing the triangle’s vertices are concurrent.
