Congruence Exploration 2 - Reflections in Intersecting Lines
- Vincent Tran
Work with a partner.
c. Find the measure of angle EDF. Rotate triangle ABC counterclockwise about point D using an angle twice the measure of angle EDF.
d. Make a conjecture about the figure reflected in two intersecting lines. Test your conjecture by changing triangle ABC and the lines.
f. From Exploration 1 and 2, what conjectures can you make about a figure reflected in two lines?
