Question

The measurements of a triangle are given. Is there exactly one triangle that can be formed using the given measurements? If so, identify the appropriate triangle congruence postulate.∆ABC : m ∠A = 90°, AB = 15, AC = 15

Answer 1

Let us make the triangle that can be formed

So from the diagram above, yes only one type of triangle can be formed. This triangle is known as Isosceles Right-triangle.

The triangle Congruence is known as Hypotenuse Leg
