The "if" part of a statement is known as...
The hypothesis

What are the slope and midpoint formulas?
slope = (y2 - y1/x2-x1)
midpoint = (x1+x2/2 , y1+y2/2)
How can you tell if two lines are parallel or perpendicular, given their slope?
parallel - same slope
perpendicular - opposite reciprocal slope
Two lines that intersect at a 90 degree angle
Perpendicular Lines
The "then" part of the statement is known as...
The conclusion
