Review of Transversals and angles

2.  Last time we talked about Vertical
Angles. Like these:

3.  And these:

4.  And these:

5. Lets Review…..
 We also talked about
congruent.
 What does CONGRUENT
mean?
 CONGRUENT = SAME SAME

6. Vertical Angles
If A is 105°
What is C?
105°

7. Vertical Angles
110°
Let’s try a few more….
110°
?

8. Vertical Angles
84°
Let’s try a few more….
84°
?

9. Vertical Angles
78°
Let’s try a few more….
78°
?

10. Corresponding Angles
 Corresponding Angles also have equal
measures.
 When the two angles have the same
measure, they are called congruent.

11.  Last time we also talked about
CORRESPONDING ANGLES.
Like these:

12.  And these:

13.  And these:

14. Corresponding Angles
If B is 88°
What is F?
88°

15. Corresponding Angles
127°
Let’s try a few more….
127°
?

16. Corresponding Angles
77°
Let’s try a few more….
77°
?

17. Corresponding Angles
73°
Let’s try a few more….
73°
?

18. Co-interior Angles
When you know the
degree of 1 co-interior
angle but not the
other, just subtract it
from 180.

19. Co-Interior Angles
Like these….

20. Co-Interior Angles
64°
Like these….
?

21. Co-Interior Angles
64°
180 - 64 = 116
116°?

22. Co-Interior Angles
81°
Let’s try another….
99°
?
