1. True 2. True 3. False-It would be true if the lines were parallel, but they are not. Therefore, <4 and <7 are not corresponding angles. 4. False-<4 is 80 degrees and <7 is 90 degrees. 5. True 6. False-<8 measures 90 degrees because its vertical angle is 90 degrees. 7. False-Line o is not parallel to lines m and n because m and n has 100 degree and 80 degrees angle measures, but line o only has 90 degrees angle measures 8. True
