Geometry Vocabulay

There is a great deal of vocabulary that students need to understand in order to effectively converse about 2-D geometry. Here are the terms we have discussed so far:

  • Polygon
  • Point
  • Line
  • Line Segment
  • Perpendicular Lines
  • Parallel Lines
  • Right Angle
  • Acute Angelo
  • Obtuse Angle
  • Triangle
  • Quadrilateral
  • Pentagon
  • Hexagon
  • Heptagon / Septagon
  • Octagon
  • Decagon
We'll be adding to this list often as we explore further geometric ideas. Ask your 4th grader to explain these terms to you!
