What is a rotation?
the circular movement of an object around a centre
What is a reflection?
Reflection in math definition is the mirror image of a figure over a line (drawn or imaginary), known as the line of reflection, or over a point, known as the reflection point.
What is a Dilation?
the action or condition of becoming or being made wider, larger, or more open.
What is a angle?
a figure which is formed by two rays or lines that shares a common endpoint
What is a translation?
moves a shape left, right, up, or down but does not turn.
