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

An acute triangle is one whose angles are all less than 90 degrees.

An Isosceles triangle is a triangle with two sides the same length.

Answer 2

combining those two here is an example
a triangle with angles equal to 75°, 75°, and 30°. The triangle is an isosceles and all three angles are acute.

Answer 3

this is for part 1
