a. 2. a->b is transversal
b. Statement: a and b are supplementary
Reason: angle a is 145 deg and angle b is 35 deg, the two angles add up to 180 degrees.
c. If you measure one angle and then subtract it from 180 you get the other angle.
3. The exterior angles
a. a and 2 are both 145 deg, 1 and b are both 35 deg
b. the fact that you can subtract one from 180 to get the other.
c. 145 degrees
4. Reflection
a. train tracks, roads.
b. The fact that the slope exists is a fairly major issue, using imaginary concepts allows for more freedom of geometric expression, an example of this is basically all of subspace and hyperspacial theory. Since it is purely theoretical and thus imaginary greater freedom is offered to generate theories and structures.
