What is the Angle Bisector Theorem?

Back

The Angle Bisector Theorem states that if a point lies on the angle bisector of an angle, then it is equidistant from the two sides of the angle.

How can you find the length of an angle bisector in a triangle?

Back

The length of an angle bisector can be found using the formula: l = (2ab)/(a+b) * cos(C/2), where a and b are the lengths of the sides adjacent to the angle, and C is the angle.

What is the significance of the incenter in a triangle?

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is the center of the inscribed circle (incircle) of the triangle.

What is the relationship between the inradius and the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = r * s, where r is the inradius and s is the semi-perimeter of the triangle.
