Here is a diagram showing triangle ABC and some transformations of triangle
ABC
On the left side of the diagram, triangle ABC has been reflected across line AC to
form quadrilateral ABCD. On the right side of the diagram, triangle ABC has
been rotated 180 degrees using midpoint M as a center to form quadrilateral
АВСЕ.
Using what you know about rigid transformations, side lengths and angle
measures, how long are the following sides: AD, CD, AE, and EC? What are the
angle measures for the following angles: ADC and AEC?
