What is a transformation in geometry?

Back

A transformation is a function that maps a geometric figure onto another figure, changing its position, size, or orientation.

Front

What is translation in geometry?

Back

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

Front

What is 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.

Front

What is reflection in geometry?

Back

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

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, meaning all corresponding sides and angles are equal.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size, with proportional sides and congruent angles.

Front

What is the angle of rotation for a 90-degree clockwise rotation?

Back

A 90-degree clockwise rotation turns a figure to the right, moving points in a circular path around the center of rotation.

Front

What is the angle of rotation for a 180-degree rotation?

Back

A 180-degree rotation turns a figure upside down, placing it in the opposite position.

Front

What is the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.
