Front

Can the sides of a triangle have lengths 3, 8, and 9?

Back

Yes

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

If two angles of a triangle are known, how can you find the third angle?

Back

Subtract the sum of the known angles from 180°.

Front

What is the relationship between the lengths of the sides and the angles of a triangle?

Back

The largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.

Front

How do you determine if a triangle is valid based on its side lengths?

Back

Check if the sum of the lengths of any two sides is greater than the length of the third side.
