Lesson: Reflections Mathematics

In this lesson, we will learn how to reflect points and shapes in given reflection lines.

Lesson Plan

Students will be able to

define the reflection of a point in a straight line using perpendicular bisectors,
use the construction of a perpendicular bisector to reflect points in a given straight line,
use the construction of a perpendicular bisector to reflect line segments in a given straight line,
use the construction of a perpendicular bisector to reflect shapes in a given straight line,
reflect a shape in a straight line, where the line intersects the shape or is coincident with one of the shape’s sides.
