Relationships in Triangles Review

Front

Can a triangle be formed with side lengths: 10, 12, 22?

Back

No, the sum of the lengths of the two shorter sides (10 + 12 = 22) must be greater than the length of the longest side (22).

Front

If segment YW is an altitude, which statement is true?

Back

∠YWZ is a right angle, as an altitude creates a right angle with the base.

Front

Back

R, P, Q.

Front

Name the sides from SMALLEST to LARGEST: RS, ST, TR.

Back

RT, RS, ST.

Front

Which of these is a perpendicular bisector? segment KI, ray GL, line JM, line HJ.

Back

Line JM is a perpendicular bisector.

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

Define an altitude in a triangle.

Back

An altitude is a segment from a vertex perpendicular to the line containing the opposite side.

Front

What is the definition of a median in a triangle?

Back

A median is a segment from a vertex to the midpoint of the opposite side.

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

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

Back

In a triangle, the larger angle is opposite the longer side.
