6-2 Properties of Parallelograms
DODEA Standard
G.1.1: Demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning;
G.3.1: Identify and describe characteristics of convex, concave, and regular polygons;
G.3.2: Describe, classify, and explain relationships among the quadrilaterals square, rectangle, rhombus, parallelogram, trapezoid, and kite;
G. 3.5: Determine and use measures of sides and of interior and exterior angles of triangles, quadrilaterals, and other polygons to classify figures, develop mathematical arguments about geometrical relationships, and solve problems.
Objective
To use relationships among sides and angles of parallelograms
To use relationships among diagonals of parallelograms
