Enduring Understanding

 

The student will understand:

  • The language of geometry allows us to communicate in a precise and efficient manner.
  • Logical reasoning creates a higher lever of thinking used throughout geometry
  • Relationships exist among the angles, sides, lengths, perimeters, areas and volumes of geometric figures and can be used to prove theorems
  • A variety of representations, tools and technology can be used to solve meaningful problems by representing and transforming figures and analyzing relationships.
  • Specifying locations and describing spatial relationships using coordinate geometry and other representational systems can solve meaningful problems.

 


 

Essential Questions

 

  • Why are symbols important in geometry?
  • How does finding a midpoint apply to real world situations?
  • Why are there different classifications of angles?
  • If I'm going to be a doctor, how can geometry help me?
  • When is winning an argument not really winning an argument?
  • How are the properties of algebra and geometry related?
  • When are lines parallel? Perpendicular?
  • How are triangles classified?
  • When are triangles congruent?
  • How are unknowns found in triangles?
  • What do we need to know about two triangles to know if they are congruent, and once we know they are, what else do we know?
  • Why are some triangles special?
