Question

Write a coordinate proof to prove that the large triangle in the center of the flag is isosceles. The dimensions of the flag are 4 feet by 6 feet and point B of the triangle bisects the bottom of the flag.

Answer 1

ΔACD ≅ ΔBCE so DC = EC therefore the triangle will isosceles triangle.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

In the given figure

AC = CB , DA = EB and ∠A = ∠B

So,

ΔACD ≅ ΔBCE

Now corresponding sides of a congruent triangle are the same.

So,

DC = EC therefore the triangle will isosceles triangle.

Hence "ΔACD ≅ ΔBCE so DC = EC, therefore, the triangle will isosceles triangle".
