1. Warm Up 1. 4. 3. 2.

10. Use Labsheet 1.1

11. What size/type angles are formed by the segments connecting each vertex and the line of symmetry? 90° or right angles

12. 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’

13. 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)

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