Identify each pair of angles as alternate interior, alternate exterior,
corresponding angles, or none of these.
- 6 and 10 2. 7 and 9
- 6 and 12 4. 5 and 10
- 8 and 12 6. 8 and 10
Use the figure to find each measure.
- m5 when m 3 80°
- m2 when m 6 150°
- m8 when m 3 65°
- m7 when m 1 75°
- m4 when m 5 60°
- In the figure below, AB CD.
EFand GFare transversals. If
m 4 80° and m 5 40°, find the
measures of the remaining angles.
- In the figure below, points A, B, and
Eare on the same line. BD AC. If
mA65° and mC80°, find
mCBE.
- In the figure at the right, ABCD, EF
intersects AB at Gand CDat H, and
MHbisects CHG. Find mMHC.
