Answer 2

Answer:

Say something along the lines of ¨This triangle is not a right triangle because it has no right angles, instead it is an isosceles triangle. This is because it has 2 sides that are perfectly equal. It also can be obtuse or acute because it has no obtuse/acute angles. This triangle also has two equal angles (A and C) these angles are the smaller angles. The angle B is a big angle so B+A+C=180 degrees.¨
