1. PARALLEL LINES
Cut by a transveral

2. Copy the following picture in your notebooks and label correctly

3. If 2 Parallel lines are cut by a transversal, then alternate interior angles are congruent

4. If 2 Parallel lines are cut by a transversal, then corresponding angles are congruent

5. If 2 Parallel lines are cut by a transversal, then alternate exterior angles are congruent

6. If 2 parallel lines are cut by a transversal, then same side interior angles are supplementary

7. a = a
o = o
a + o = 180
Hint for algebraic problems: O a a O a O a O
