What is a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in a specified direction.

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 criteria like ASA, SAS, or AAS.

Front

What is the ASA criterion for triangle congruence?

Back

ASA stands for Angle-Side-Angle; it 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 SAS criterion for triangle congruence?

Back

SAS stands for Side-Angle-Side; it 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 AAS criterion for triangle congruence?

Back

AAS stands for Angle-Angle-Side; it 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 a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie on opposite sides of a transversal and inside the two lines it intersects; they are equal when the lines are parallel.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal; they are equal.

Front

What is the relationship between same side interior angles?

Back

Same side interior angles are pairs of angles that lie on the same side of the transversal and between the two lines; they are supplementary when the lines are parallel.

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.
