IM 8th Math Unit 1 Mid-Unit Assessment Review

Front

What happens when parallel lines are rotated 180° counterclockwise about the origin?

Back

The lines remain parallel.

Front

A 76° angle is reflected across the x-axis. What is the measure of the angle in the image?

Back

76 degrees.

Front

What is the angle of rotation for a counterclockwise rotation about the origin that results in a 270° turn?

Back

270°.

Front

How many degrees was the figure rotated if it was turned 180°?

Back

180°.

Front

What transformation is shown for the letter F if it is turned around a point?

Back

Rotation.

Front

Define parallel lines in geometry.

Back

Lines that never intersect and are always the same distance apart.

Front

What is the definition of reflection in geometry?

Back

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

Front

What does a 90° counterclockwise rotation look like on a coordinate plane?

Back

The figure moves to the left and up, changing its coordinates accordingly.

Front

What is the result of reflecting a point (x, y) across the x-axis?

Back

The new point is (x, -y).

Front

Explain what a transformation is in geometry.

Back

A change in the position, size, or shape of a figure.
