Question

A triangle can be classified by its angles and by its sides.

Part 1: Use these two ways of classification to describe an acute isosceles triangle.

Part 2: Name a triangle with only a different angle classification as an acute isosceles. Identify one similarity and one difference between this new triangle and the acute isosceles triangle.

Answer 1

You can use angle measurement and side length to classify triangles.

Acute triangles angles that are all less than 90 degrees. Isoceles have 2 legs that are the same length, or two angles that are the same.
