So, what's with the biscuits?

Oh a triangulator machine! Very cool!

Right, there are four different types of triangle.

First, here's an isosceles triangle, it has two equal length sides and two equal angles.

Oh! Very clever!

Now we have an equilateral triangle. Three sides of equal length andall the angles are 60 degrees.

This is a scalene triangle. All the sides are different lengths and each angle is different as well.

This one’s a right angled triangle, where one angle is always a right angle, so that's 90 degrees.

Excellent stuff!

Right, let's get you back to normal.

Oh…Uhh…Oh dear.

It's fine.
