Description
The student will define midsegment, median, centroid, perpendicular and angle bisectors, and altitude
of triangles. They will apply and prove properties of these parts of triangles and use the coordinate plane to complete proofs.
Timeline
2.5 Week(s)
Enduring Understandings
Properties of triangles can be proved using a coordinate plane.
Special segments of triangles are classified based on the different properties.
Essential Questions
How do you use prior knowledge to prove a new idea?
How do algebraic concepts relate to the segments and angles within a triangle?
How can the coordinate plane be used to prove properties of triangles?
