This will be externally assessed and is worth 4 credits.
Note that will be around 30 rules to learn off by heart. The first 10 or so we will call "Angle Rules". We will number them as we go so you know that you have them all. |
Rules 6, 7, 8
All angles in an equilateral triangle are equal to 60 degrees.
The angle sum of an isosceles triangle is 180 degrees - can use if finding the top angle.
The exterior angle of a triangle is equal to the the sum of the interior opposite angles.
