Midterm Test Practice

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What is the Reflexive Property?

Back

A property stating that any geometric figure is congruent to itself. For example, if line segment AB is equal to line segment AB.

Front

What does AA ~ mean in triangle similarity?

Back

AA ~ means that two triangles are similar if two angles of one triangle are equal to two angles of another triangle.

Front

What are Complementary Angles?

Back

Two angles that add up to 90 degrees.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

What is a Transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the definition of Similar Figures?

Back

Figures that have the same shape but not necessarily the same size, with corresponding angles equal and corresponding sides proportional.

Front

What is the similarity statement for triangles?

Back

A statement that indicates two triangles are similar, such as ΔABC ~ ΔDEF.

Front

What is the relationship between angles formed by a transversal and parallel lines?

Back

When a transversal intersects parallel lines, corresponding angles are equal, and alternate interior angles are equal.

Front

What is the Sum of Angles in a Triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.
