Geometry Transformations

Front

What is a translation in geometry?

Back

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

Front

What is the rule for translating a point (x, y) by 2 units to the right and 1 unit down?

Back

(x + 2, y - 1)

Front

How do you reflect a point (x, y) over the y-axis?

Back

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

Front

What is the result of reflecting the point (-5, 2) over the y-axis?

Back

(5, 2)

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is the angle of rotation for a 90 degrees clockwise rotation?

Back

The figure is rotated 90 degrees in the direction of the clock hands.

Front

What is the effect of a reflection across the x-axis on a point (x, y)?

Back

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

Front

What is the result of reflecting the point (3, -4) over the x-axis?

Back

(3, 4)

Front

What is a composition of transformations?

Back

A composition of transformations is when two or more transformations are combined to produce a single transformation.

Front

What is the result of reflecting a figure over the y-axis and then rotating it 90 degrees?

Back

The figure's position and orientation will change based on the transformations applied.
