Chapter 3 Geometry
Traversals and Parallel Lines
| Term | Definition |
|---|---|
| Alternate Exterior Angles | Two non adjacent exterior angles that lie on opposite sides of the transversal |
| Alternate interior Angles | Two nonadjacent interior angles that lie on opposite sides of a transversal. |
| Corresponding angles | Two nonadjacent angles, one interior and on exterior that lie on the same side of a transversal. |
| same side interior angles | Interior angles that lie on the same side of a transversal. |
| slope | m of a line is the ratio of the vertical change Rise over Run |
| slope intercept form | y = mx +B |
| Point Slope Form | y - y1 = m (x - x1) |
| Parallel Lines | are coplanar lines that do not intersect. |
| Skew Lines | Are non complanar, they are not parallel and do not intersect |
| Parallel planes | planes that do not intersect |
| Transversal | A line that intersects two or more coplanar lines at distinct points. |
| Supplementary angles | angles that equal 180 |
| complementary angles | angles that equal 90 |
