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.
