ΔCAT is an isosceles triangle with vertex angle A. If the measure of angle A equals 80 degrees , then find the m∠T. (Hint: Draw and label the triangle)

Answer 1

Since triangle CAT is an isosceles triangle, we know that angles C and T are congruent.

Given that angle A = 80 degrees, we know that angles C and T together must add up to 100 degrees (since the sum of the angles in a triangle is always 180 degrees).

Therefore, each of angles C and T must be 50 degrees.

So, m∠T = 50 degrees.
