2. New Vocabulary Congruent Transversal Vertical Angles Adjacent Angles
Corresponding Angles
Alternate Interior Angles
Alternate Exterior Angles
Consecutive Interior Angles

3. Congruent
The same size

4. Transversal
A line that crosses a set of parallel lines

5. Vertical Angles
Vertical Angles are the angles opposite each other and share the same vertex
vertical angles are equal

6. Corresponding Angles
The angles in matching corners are called Corresponding Angles.
Think about if you cut and placed

7. Alternate Interior Angles
The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles.
Alternate Interior angles are congruent

8. Alternate Interior Angles
3 6
5 4

9. Alternate Exterior Angles
The pairs of angles on opposite sides of the transversal but outside the two lines are called Alternate Exterior Angles.
These angles are congruent

10. Alternate Exterior Angles
2 8
1 7

11. Consecutive Interior Angles
The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles.
Their sum is 180°

12. Consecutive Interior Angles

13. Adjacent Angles
Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.
Angle ABC is adjacent to angle CBD
Because: they have a common side (line CB) they have a common vertex (point B)

14. Adjacent Angles
Adjacent Angles
1 and 2
3 and 4
5 and 6
7 and 8
