What is the distance from:A to line mA to line m

B to line mB‘ to line m

C to line mC‘ to line m

D to line mD‘ to line m

E to line mE‘ to line m

What size/type angles are formed by the segments connecting each vertex and the line of symmetry?

90° or right angles

The line of reflection is perpendicular to each segment at its midpoint.The line of reflection is the “perpendicular bisector” of each segment joining a point to its image.

A is in the same location as A’ and E is also in the same location as E’

1. Connect pairs of corresponding points on each part of the design.

2. Find the midpoint of one of the segments.

3. Draw a line that is the “perpendicular bisector” of each segment. (90 degree angle)

XX’ is perpendicular to line m and points X and X’ are equidistant from line m.
