Congruence and Corresponding Parts

Front

What is congruence in geometry?

Back

Congruence means that two figures have the same shape and size. They can be superimposed on each other.

Front

What are corresponding parts in congruent figures?

Back

Corresponding parts are the sides and angles of congruent figures that match each other.

Front

What is a rigid transformation?

Back

A rigid transformation is a movement of a figure that does not change its shape or size, only its position.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a figure into two mirror-image halves.

Front

What does a 90-degree clockwise rotation do to a figure?

Back

A 90-degree clockwise rotation turns a figure 90 degrees to the right around a point.

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 a figure from one place to another without changing its shape or size.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

How do you identify a line of symmetry in a shape?

Back

A line of symmetry can be identified by folding the shape along the line and seeing if both halves match.

Front

What is the effect of a 180-degree rotation on a figure?

Back

A 180-degree rotation turns a figure upside down around a point.
