Lines and Angles Geometry Farris 2015

 I can identify parallel, perpendicular and skew lines.  I can identify the angles formed by two lines and a transversal.

Definitions  Parallel lines – coplanar and do not intersect (ll)  Perpendicular lines – intersect at 90° angles ( )  Skew lines – not coplanar, parallel, and do not intersect  Parallel planes – planes that do not intersect

Parallel Planes

Definitions  Transversal – a line that intersects two coplanar lines at two different points.

 Corresponding angles – lie on the same side of the transversal  Alternate interior angles – nonadjacent angles that lie on opposite sides of the transversal  Alternate exterior angles – lie on opposite sides of the transversal  Same-side interior angles – (constructive interior angles) lie on the same side of the transversal
