Geometry 1st Semester Review

Front

What is the measure of ∠3 if ∠2 is 83°?

Back

97°

Front

What theorem can be used to prove two triangles are congruent if two angles and the included side are known?

Back

ASA (Angle-Side-Angle)

Front

What is the contrapositive of a conditional statement?

Back

The contrapositive of a statement 'If P, then Q' is 'If not Q, then not P'.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, which is a method to prove triangle congruence.

Front

What is the SSS criterion for triangle congruence?

Back

SSS stands for Side-Side-Side, meaning if three sides of one triangle are equal to three sides of another triangle, they are congruent.

Front

What is the AAA criterion for triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which does not prove congruence, only similarity.

Front

If two angles of a triangle are known, how can the third angle be found?

Back

The third angle can be found using the fact that the sum of angles in a triangle is 180°.

Front

What is the definition of a conditional statement in geometry?

Back

A conditional statement is an 'if-then' statement, where 'if' is the hypothesis and 'then' is the conclusion.

Front

What is the definition of the inverse of a conditional statement?

Back

The inverse of a statement 'If P, then Q' is 'If not P, then not Q'.

Front

What is the definition of the converse of a conditional statement?

Back

The converse of a statement 'If P, then Q' is 'If Q, then P'.
