Question

Select the term that does not describe the triangle. Select all that apply.

acute
isosceles
right

Answer 1

It has a right angle (90 degrees) and 2 sides are equal which makes it isosceles.
So there's only one choice left.

Answer 2

Isosceles and right triangles are the right answers.

Explanation:

In the given triangle ABC, we can see that it is a right angle triangle. Angle C is 90 degrees. So, it is a right angle triangle.

Also two sides, BC and AC are 3 inches, means they are same. So, it is an isosceles triangle. The definition of isosceles triangle is that it has 2 sides equal in length.

The third option is acute triangle. This is wrong as acute triangle has all the three angles less than 90 degrees.
