Front

What is a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What are the types of triangles based on side lengths?

Back

Triangles can be classified as equilateral, isosceles, or scalene.

Front

What is an equilateral triangle?

Back

An equilateral triangle has all three sides of equal length.

Front

What is an isosceles triangle?

Back

An isosceles triangle has at least two sides of equal length.

Front

What is a scalene triangle?

Back

A scalene triangle has all sides of different lengths.

Front

What is the Triangle Inequality Theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Can a triangle exist with sides of lengths 33, 16, and 17?

Back

No, because 33 is not less than the sum of 16 and 17.

Front

How many triangles can be formed with angles 80°, 50°, and 50°?

Back

More than one unique triangle exists with the given angle measures.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.

Front

What is a unique triangle?

Back

A unique triangle is one that can be formed with a specific set of side lengths or angle measures.
