11/13 - Rotations Day 1

Front

What is a rotation in geometry?

Back

A rotation in geometry is a transformation that turns a figure around a fixed point, known as the center of rotation, by a specified angle in a specified direction.

What does a 90° clockwise rotation look like on a coordinate plane?

Back

A 90° clockwise rotation moves a point (x, y) to (y, -x) on the coordinate plane.

What is the result of rotating a figure 180° around the origin?

Back

Rotating a figure 180° around the origin transforms a point (x, y) to (-x, -y) on the coordinate plane.

How does a 360° rotation affect the position of a figure?

Back

A 360° rotation returns the figure to its original position, as it completes a full turn.

How do you determine the new coordinates of a point after a rotation?

Back

To determine the new coordinates after a rotation, apply the appropriate rotation rule based on the angle and direction of rotation.

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the direction of the hands of a clock, while counterclockwise rotation moves in the opposite direction.

What is the effect of rotating a triangle 90° clockwise?

Back

Rotating a triangle 90° clockwise will change the orientation of the triangle, moving its vertices to new positions based on the rotation rule.

What happens to the shape of a triangle when it is rotated?

Back

The shape of the triangle remains the same during rotation; only its position and orientation change.
