alternate exterior angles
- Bradley Miller
Given: Lines f and g are parallel.
Make a conjecture about the relationship of the measures of the highlighted angles.
How do you think they relate?
Test your conjecture!
Click the “Show Angle Measures” button and test your theory from above. Were you correct?
Click and drag point C until lines g and f overlap completely.
What do you notice about the relationship between the two angles of interest?
Tell me more!
Deduce the angle measures of 4 other angles in the diagram.
