Transversal=a line that intersects to coplanar lines at 2 different points
Corresponding angles=Angle that are on the same side as the transversal
Alternate interior angles=angles that are on different sides of the transveral, but are in between the 2 other lines
Alternate exterior angles=Angles that are on different sides of the transversal and are on the opposite sides of the 2 other lines
Same side interior angles= Angles that are on teh same side of the transversal and on teh inside of the 2 other lines
---------- = Parallel Lines
|________ = Perpendicular Lines
|
Proving Lines are Parallel
1.Converse of the alternate interior angles
2.Converse of the alternate exterior angles
3.Converse of the same-side interior angles
4.Converse of the corresponding angles
5.If 2 lines are perpendicular to the same line the they must be parallel ----------- ^
Finding the Slope
Equation: y1-y2 = once you find the answer you divide the top number by the bottom and thast the slope.
x1-x2
5-3 = 2 = 1 4-2 2
