Coplanar lines that do not intersect.
Lines that don't intersect and are not coplanar.
A line that intersects two or more coplanar lines at different points.
Consecutive Interior Angles
Interior angles that lie on the same side of the transversal.
Alternate Interior Angles
Nonadjacent interior angles that lie on opposite sides of the transversal.
Alternate Exterior Angles
Nonadjacent exterior angles that lie on opposite sides of the transversal.
Nonadjacent angles that lie on the same side of the transversal, where one angle is in the interior and the other on the exterior.
The ratio of change along the y-axis between any two point on a line.
Lines that intersect to form right angles.
The distance between two lines measured along a perpendicular to the lines is always the same.
y= mx + b (where m= slope and b= the y-intercept)
y- y1= m(x-x1)
