Look at the x and y- coordinate grid below.

The points (4,2), (6,7) and (8,2) have been plotted.

When we plot coordinates, remember the first number is for the x-axis and the second number is for the y-axis.

The **x-axis is the horizontal line** at the bottom and the** y-axis is the vertical line **going up the left-hand side but, don't worry, they're labelled for you!

The shape formed is an** isosceles triangle.**

An** isosceles **triangle is a triangle that has two of its sides and two of its angles the same.

An** equilateral** triangle is a regular shape - this means it has all of its sides and angles the same size.

A **scalene** triangle is a triangle where all three angles are different and all three sides are different.

A **right-angled t**riangle has a right angle in it - this is when two of its sides meet at a 90 degree angle.

Let's try some questions now. You will need some paper and a pencil so that you can sketch out your coordinate grid each time.
