What does rotation mean in geometry?

Rotation helps us to align the figures in the direction along with a fixed point.

Answer: Rotation in geometry is a motion of a figure along with one fixed point.

Let us understand the concept with an image.

Explanation

Look at the image shown below.

O is the fixed point of rotation. Along with point O, the triangle is rotated clockwise.

Hence, rotation in geometry is a motion of a figure along with one fixed point.
