If PR = 32 and QR = 15, how do you find PQ in a triangle?

Back

Use the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side.

Front

How do you determine if a triangle is valid with given side lengths?

Back

A triangle is valid if the sum of the lengths of any two sides is greater than the length of the third side (Triangle Inequality Theorem).

What is the significance of the right angle in a triangle?

Back

The right angle (90 degrees) in a triangle indicates that it is a right triangle, which allows the use of the Pythagorean theorem to find unknown side lengths.

What does it mean for a polygon to be regular?

Back

A regular polygon is a polygon with all sides and all angles equal.
