Standards Addressed
MGSE.9-12.G.CO.10: Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180 degrees, base angles of isosceles triangles are congruent, the segment joining midpoints of two sides of a triangle is parallel to the 3rd side and half the length, medians of a triangle meet at a point.

Learning Targets /Success Criteria:
--I can classify triangles by their sides and angles.
--I can prove if three side lengths form a triangle.
--I can order sides and angles of triangles from smallest to largest.
--I can identify the range for a possible third side of a triangle.
