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


2D Shapes

Here is a great website FULL of 2D shapes!

*Remember, polygons are closed figures made up of at least 3 line segments.

*Some shapes have many names like a square. A square can be called a: parallelogram, quadrilateral, rhombus, and even a rectangle!
