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 triangle has a right-angle in it - this is when two of its sides meet at a 90 degree angle.
