STEM Transformations

Front

What is the definition of rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

Front

What is a translation in geometry?

Back

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

Front

What is a reflection in geometry?

Back

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

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure rotates.

Front

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree to which a figure is rotated around a center point.

Front

What happens to the coordinates of a point (x, y) when it is rotated 90° counterclockwise about the origin?

Back

The new coordinates will be (-y, x).

Front

What happens to the coordinates of a point (x, y) when it is rotated 180° about the origin?

Back

The new coordinates will be (-x, -y).

Front

What happens to the coordinates of a point (x, y) when it is rotated 270° counterclockwise about the origin?

Back

The new coordinates will be (y, -x).

Front

What is the result of rotating a figure 360°?

Back

Rotating a figure 360° results in the figure being in its original position.

Front

What is the difference between rotation and reflection?

Back

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