What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

If ∠C is 40° in triangle ABC and triangle ABC is congruent to triangle DEF, what is the measure of ∠F?

Back

50°

Front

What is the definition of the SSS (Side-Side-Side) Congruence Theorem?

Back

The SSS Congruence Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

What is the definition of the SAS (Side-Angle-Side) Congruence Theorem?

Back

The SAS Congruence Theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape. Common transformations include translation, rotation, and reflection.

Front

What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Front

How can you determine if two figures are congruent using transformations?

Back

Two figures are congruent if one can be transformed into the other using a series of transformations such as translations, rotations, and reflections.

Front

What does the term 'corresponding parts' refer to in congruent triangles?

Back

Corresponding parts refer to the sides and angles of congruent triangles that match each other in position and measure.
