Lesson 1.1 – Line Reflections

11. Use Labsheet 1.1

12. What is the distance from:
A to line m
A‘ to line m
B to line m
B‘ to line m
C to line m
C‘ to line m
D to line m
D‘ to line m
E to line m
E‘ to line m
What size/type angles are formed by the segments connecting each vertex and the line of symmetry?
90° or right angles

13. 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’

14. Connect pairs of corresponding points on each part of the design.
Find the midpoint of one of the segments.
Draw a line that is the “perpendicular bisector” of each segment. (90 degree angle)

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