The perimeter of an isosceles triangle is 19.5 m, and the lateral side is 7.6 m, into which lengths the base of the triangle

The perimeter of an isosceles triangle is 19.5 m, and the lateral side is 7.6 m, into which lengths the base of the triangle divides the bisector of the apex angle.

The perimeter of a triangle is equal to the sum of the lengths of its three sides. A bisector drawn from the apex of an isosceles triangle divides the base in half.

1. Determine the length of the base of an isosceles triangle.

19.5 – 7.6 * 2 = 19.5 – 15.2 = 4.3 meters.

Let’s answer the question of the problem.

2. Let’s find out into segments of what length the bisector of the angle at the vertex will divide the base of the triangle.

4.3 / 2 = 2.15 meters.

Answer: The bisector will divide the base of the triangle into segments equal to 2.15 meters.
