Unit 5 Transformations Flashcard (Translation/Reflection/Rotation)

Front

Describe the transformation: T < 3, 0 > (x, y)

Back

Translate 3 units right.

Front

What would the new point be if you rotated the point (3,-5) 270° counterclockwise?

Back

(-5,-3)

Front

Describe the transformation: (x, y) -> (-y, x)

Back

Rotation 90 degrees counterclockwise.

Front

What does it mean if two figures are congruent?

Back

Same size and shape.

Front

What is a translation in geometry?

Back

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

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

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

Front

What is the effect of a 90-degree clockwise rotation on the point (x, y)?

Back

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

Front

What is the effect of a 180-degree rotation on the point (x, y)?

Back

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

Front

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

Back

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