What is Translation?
A translation is a transformation that moves every point in a figure the same distance in the same direction

What are Rotations?
Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point.
100
What Are Reflections?
In mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis or plane of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection.

What are dilations?
Dilation is the process of enlarging or reducing the size of a geometrical object without changing its shape. This is done by using the scale factor which helps in increasing or decreasing the size of the object.

What are Angles
an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays.
