Recunoasteti triunghiurile isoscele din figurile de mai jos:
yarga [219]

Answer:

<h2>The right side triangle is isosceles and equilateral.</h2>

Step-by-step explanation:

In this problem we need to draw isosceles triangles with AB=AC. The triangle is attached.

Also, we have to identify which triangle is isosceles based on the image. The triangle on the left is isosceles and equilateral. Remember that a isosceles triangle is defined by the congruence between at least two sides, in this case, we have three congruent sides, which makes the triangle isosceles and equilateral.

The triangle on the right side is not isosceles, it's just a right triangle. When a right triangle is also isosceles, its acute angles are 45°, which is not the case here.
