Final answer:
A reflection in mathematics is when a figure in the coordinate plane flips either over the x-axis or y-axis.
Step-by-step explanation:
In mathematics, a reflection is when a figure in the coordinate plane flips either over the x-axis or y-axis. This means that each point of the figure moves to an equal distance on the opposite side of the axis. For example, if we have a point (3,5) and we reflect it over the x-axis, it will become (3,-5) since it moves the same distance on the opposite side of the axis.
