### Test Tues

Remember to study for the test Tues. Practice proving parallel lines, finding angles of parallel lines, determining whether lines are parallel or perpendicular or neither based on the slope between points or their equations.

Perpendicular slopes are like contrapositive in logic. (change order and negate)

Transitive is like syllogism.

Substitution is replacing an equal value into a different expression. As in: If m<4 =m<3 and <4 is supplementary to <2 then ❤ is supplementary to <2.

### Test Monday
