MATH 2 - FINAL EXAM REVIEW

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape, defined by a scale factor (k).

Front

If a dilation with a scale factor of k=2 is applied to the point A (0, 3), what is the x value of A'?

Back

0

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

If a dilation with a scale factor of k=0.5 is applied to the point A (-1, 6), what is the y value of A'?

Back

3

Front

How do you factor the expression x² + 11x + 24?

Back

(x + 8)(x + 3)

Front

What does the SSS postulate state?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the SAS postulate?

Back

The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the ASA postulate?

Back

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the AAS postulate?

Back

The AAS (Angle-Angle-Side) postulate states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the HL postulate?

Back

The HL (Hypotenuse-Leg) postulate states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.
