Classifying Triangles Practice

Front

What are the three main types of triangles based on their sides?

Back

1. Equilateral: All sides are equal. 2. Isosceles: Two sides are equal. 3. Scalene: All sides are different.

Front

What are the three main types of triangles based on their angles?

Back

1. Acute: All angles are less than 90 degrees. 2. Right: One angle is exactly 90 degrees. 3. Obtuse: One angle is greater than 90 degrees.

What is the sum of the interior angles of any triangle?

Back

180 degrees.

Front

What is the relationship between the sides and angles in a triangle?

Back

In a triangle, the largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.

Front

How can you determine if a triangle is right-angled?

Back

If one of the angles measures exactly 90 degrees.
