Rigid Motions & Dilations in Geometry

In this unit we’ll work with two dimensional geometric figures on the coordinate plane. We will focus on these skills.

  • Review plotting points
  • Review the coordinate plane basics
  • Learn and practice translations
  • Learn and practice rotations
  • Learn and practice reflections
  • Learn and practice dilations
  • Determine a possible sequence of motion that could create a situation
  • Understand congruence using rigid motions
  • Understand the interior and exterior angles of a triangle by way of rigid motions
  • Find unknown sides of a triangle using Pythagorean Theorem
