Ineed with 1-8 and if they’re false, i need just a short explanation on why

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
