Midterm Test Review

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but not necessarily the same size. Their corresponding angles are equal, and their corresponding sides are proportional.

Front

What is the Linear Pair Postulate?

Back

The Linear Pair Postulate states that if two angles form a linear pair, they are supplementary, meaning their measures add up to 180 degrees.

Front

What is the Vertical Angles Theorem?

Back

The Vertical Angles Theorem states that when two lines intersect, the opposite (or vertical) angles are equal.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What is the converse of a statement?

Back

The converse of a statement is formed by reversing the hypothesis and conclusion. For example, the converse of 'If A, then B' is 'If B, then A'.

Front

What is the contrapositive of a statement?

Back

The contrapositive of a statement is formed by negating both the hypothesis and conclusion and reversing them. For example, the contrapositive of 'If A, then B' is 'If not B, then not A'.

Front

What does the similarity statement ΔXYZ~ΔNEW indicate?

Back

The similarity statement ΔXYZ~ΔNEW indicates that triangle XYZ is similar to triangle NEW, meaning their corresponding angles are equal and their corresponding sides are proportional.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two different parallel lines cut by a transversal.

Front

What is the definition of proportional sides?

Back

Proportional sides are sides of two or more figures that have the same ratio in length.

Front

What is the definition of a quadrilateral?

Back

A quadrilateral is a polygon with four sides, four vertices, and four angles.
