Units 1-2 Review

Front

Find K' if the figure is reflected across the x-axis: (1, -4)

Back

(1, 4)

Front

Name the angle relationship: Vertical Angles

Back

Vertical angles are formed when two lines intersect, creating two pairs of opposite angles that are equal.

Front

Describe the sequence of transformations: Reflect across the x-axis and then rotate 90º clockwise around the origin

Back

This transformation involves flipping the figure over the x-axis and then rotating it 90 degrees clockwise.

Front

What is the original figure prior to a transformation?

Back

Pre-image is the term used to describe the original figure before any transformations are applied.

Front

Identify the transformation from ABC to A'B'C': 90º clockwise rotation

Back

This transformation involves rotating the figure 90 degrees in the clockwise direction.

Front

What is the definition of a reflection in geometry?

Back

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

Front

What is the definition of a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the definition of a translation in geometry?

Back

A translation is a transformation that moves a figure from one location to another without changing its shape or orientation.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal.
