Concept # 1. Introduction to parallelograms
Learning objectives
- A 4-sided flat shape with straight sides where opposite sides are parallel.
- Also opposite sides are equal in length, and opposite angles are equal.
- Squares, Rectangles and Rhombuses are all Parallelograms.
- Properties of a parallelogram are :
a. Opposite sides parallel
b. Opposite sides equal
c. Diagonals bisect each other
d. Opposite angles congruent
e. Consecutive angles supplementary.
Notes for teachers
Activity No # 1. Introducing parallelograms
- Estimated Time : 40 minutes.
- Materials/ Resources needed:
Laptop, geogebra file, projector and a pointer.
