Unit 11 - Review

Front

What is a 90° Clockwise Rotation?

Back

A transformation that turns a figure 90 degrees in the clockwise direction around a fixed point.

Front

What is a 180° Rotation?

Back

A transformation that turns a figure 180 degrees around a fixed point, effectively flipping it upside down.

Front

What is a 270° Clockwise Rotation?

Back

A transformation that turns a figure 270 degrees in the clockwise direction, equivalent to a 90-degree counterclockwise rotation.

Front

What is a 360° Rotation?

Back

A transformation that turns a figure 360 degrees around a fixed point, resulting in the figure appearing unchanged.

Front

What is a reflection across the y-axis?

Back

A transformation that flips a figure over the y-axis, changing the sign of the x-coordinates of the points.

Front

What is translation in geometry?

Back

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

Front

If a point A is at (2, 5), where will it be after a translation of (x, y) --> (x+3, y-2)?

Back

A' will be at (5, 3).

Front

If point X is at (1, 4), where will it be after translating 3 units to the left and 9 units down?

Back

X' will be at (-2, -5).

Front

What does it mean to reflect a figure?

Back

To reflect a figure means to create a mirror image of it across a line, such as the x-axis or y-axis.

Front

What is the result of translating a point 5 units right and 1 unit down from (0, 0)?

Back

The new position will be (5, -1).
