We take it that you know that in a parallelogram both pairs of opposite sides are parallel.
In this investigation you will discover some other properties of parallelograms.
Step 1: Use two rulers with different widths to draw a parallelogram on tracing paper or baking paper.
Make sure that it is not a […]
Explain your findings about the four lines in this diagram and their gradients.
Match each sketch graph from column A below with a description and a fact about gradients from the other two columns.
If you also know that AB and CD are parallel which angles can you find?
What extra information do you need to find all the numbered angles?
What do you see in this 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 you see in this triangle? What […]
