Identify Transformations

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to create a new shape.

Front

What are the three main types of transformations?

Back

The three main types of transformations are translation (slide), rotation (turn), and reflection (flip).

Front

Define translation in geometry.

Back

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

Front

Define rotation in geometry.

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

Front

Define reflection in geometry.

Back

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

Front

What is the effect of reflecting a shape over the x-axis?

Back

Reflecting a shape over the x-axis changes the sign of the y-coordinates of the points of the shape.

Front

What is the effect of reflecting a shape over the y-axis?

Back

Reflecting a shape over the y-axis changes the sign of the x-coordinates of the points of the shape.

Front

What is a sequence of transformations?

Back

A sequence of transformations is a series of two or more transformations applied to a shape in a specific order.

Front

What is the result of rotating a shape 90 degrees clockwise?

Back

Rotating a shape 90 degrees clockwise moves each point of the shape to a new position that is 90 degrees around the center of rotation.

Front

What is the result of rotating a shape 180 degrees?

Back

Rotating a shape 180 degrees turns it upside down, effectively reversing its position.
