UNIT 2—Polygons in the Plane
GPS Standard(s)/Element(s) (Include the number and standard/element): MA1G2. Students will understand and use the language of mathematical argument and justification.
a. Use conjecture, inductive reasoning, deductive reasoning, counterexamples, and indirect proof as appropriate.
b. Understand and use the relationships among a statement and its converse, inverse, and contrapositive.
MA1G3. Students will discover, prove and apply properties of triangles, quadrilaterals and other polygons.
c. Understand and use congruence postulates and theorems for triangles (SSS, SAS, ASA, AAS, HL).
d. Understand, use, and prove properties of and relationships among special quadrilaterals:
parallelogram, rectangle, rhombus, square, trapezoid, and kite.
UNIT ESSENTIAL QUESTION: What are the properties of convex polygons and how are they proven?
