3D Shapes

Angles/Lines

Angles:
Acute: measures less than 90 degrees
Right: measures 90 degrees
Obtuse: measure between 90 and 180 degrees
Straight: measure exactly 180 degrees

Lines: travel in two directions and go on and on
Intersecting Lines: cross each other like an X
Perpendicular: cross at a 90 degree angle...like a t
Parallel: lines that never cross
