Use your conjectures about parallel lines and the angles formed with a third line to find the measures of the labeled angles below. Show each step you use and be sure toeach with an angle conjecture from your Angle Relationships Toolkit. Be sure to write down your in the order that you find the angles.
There are multiple correct ways to find the angle measures.
If parallel lines are cut by a transversal, then
corresponding angles have equal measures.
Vertical angles must also have equal measures.
vertical angles have equal measures.
because they are supplementary angles.
So what is
Make sure you write down your reasoning.
