Geometry Fall Semester Exam Review

Front

What is a rigid transformation in geometry?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be proven using congruence criteria such as SSS, SAS, ASA, AAS, or HL.

Front

What is the ASA congruency theorem?

Back

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

Front

What is the SSS congruency theorem?

Back

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

Front

What are corresponding segments in congruent triangles?

Back

Corresponding segments in congruent triangles are the sides that are in the same relative position in each triangle.

Front

What are corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are the angles that are in the same relative position in each triangle.

Front

If two lines are parallel, what can be said about the angles formed by a transversal?

Back

When a transversal crosses two parallel lines, several pairs of angles are formed that are congruent, such as alternate interior angles and corresponding angles.

Front

What is the definition of a quadrilateral?

Back

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

Front

What does it mean for segments to be congruent?

Back

Segments are congruent if they have the same length.

Front

What is the relationship between angles formed by intersecting lines?

Back

When two lines intersect, they form pairs of vertical angles that are congruent and pairs of adjacent angles that are supplementary.
