Butterflies, Pinwheels, & Wallpaper
Symmetry and Transformations
Problem 3.5
Focus Question:
When two parallel lines are cut by a transversal, what can be said about the angles formed? What is always true about the angle measures in a triangle? How do you know that your answers are correct?

I
Complete the following:
Point C is a reflection of _______.
Point A is a reflection of _______.
Point M is the reflection of _______.
AC is a reflection of ____, which means that their lengths are ______.
CM is a reflection of _____, so each has a length of _____.
AM is the reflection of ______.
CB is perpendicular to _____, so  AMC and AMB are ___________.
BAM  CAM, so each angle measures ______.
C  B, and each angle measures _________________________________.
Any Questions?????
(Take notes during
this discussion.)
Supplementary Angles - two angles whose measure adds up to a straight line or 180 degrees.
Complementary Angles - two angles whose measure adds up to 90 degrees.
Vertical Angles - angles that are opposite of each other when two lines cross.
Alternate Interior Angles - angles on opposite sides of the transversal, but inside the parallel lines.
Alternate Exterior Angles - angles on opposite sides of the transversal, but outside the parallel lines.

Parallel Lines - two lines
that do not intersect or
touch at any point.

Transversal - a line that
crosses, at least two,
other lines
Parallel lines cut by a transversal creates many angles with
special relationships.
Independent Practice
Using what you have learned about the angle
relationships created by parallel lines and a
transversal, identify the measure of each angle
and explain how you are able to identify the
measurement.
