Plot Simple Shapes on Coordinate Grids

In this activity, we will learn how to plot points on a set of x and y-coordinate axes and join the points with lines, forming simple shapes.

We need to be familiar with the following shapes:

isosceles triangle, right-angled triangle, square, rectangle, parallelogram.

Remember that the x-coordinate is plotted before the y-coordinate.

Example

Join (0, 0) to (2, 0)

Join (2, 0) to (1, -3)

Join (1, -3) to (-1, -3)

Join (-1, -3) to (0, 0)

Which shape has been drawn?

Answer

We have drawn a parallelogram.

Now it't time to have a go at some questions yourself.

It will help you to answer the questions if you draw a coordinate grid on paper, so maybe fetch some paper, a  pencil and a ruler before starting the questions.
