We start from this definition:
A parallelogram is a quadrilateral with both pairs of opposite edges parallel.
In this investigation you will discover some other properties of parallelograms.
Step 1: Use two different width rulers to draw a parallelogram on tracing or baking paper.
Make sure that it is […]
This diagram shows 3 sets of parallel lines. What do you notice in the diagram?
Look at the triangle with angles marked 1, 2 and 3.
Call this T.
Label angles equal to these angles. Why are they equal?
Look at the larger heavily outlined triangle.
How many copies of triangle T can […]
