| Question | Answer |
| What type of triangle is this? | Right angle triangle |
| What type of triangle is this? | Isosceles Triangle (includes two sides the same length) |
| What type of triangle is this? | Equilateral triangle (all sides and angles are the same) |
| What type of triangle is this? | Scalene triangle (all sides and angles are different) |
| Find the perimeter of this triangle: | 11 + 13 + 8 = 32cm |
| Find the perimeter of this triangle: | 9 + 12 + 7 = 28cm |
| Find the perimeter of this triangle: | 6 + 8 + 3 = 17cm |
| Find the perimeter of this triangle: | 5 + 4 + 3 = 12 |
| Find the area of this triangle: | A = bh divided by 2 = 12 x 5 = 60/2 = 30 |
| Find the area of this triangle: | Area = bh divided by 2 = 6 x 5 = 30/2 = 15cm(squared) |
| Find the area of this triangle: | Area = bh divided by 2 = 12 x 8 = 96/2 = 48cm(squared) |
| Find the area of this triangle: | Area = bh divided by 2 = 10 x 12 = 120/2 = 60cm(squared) |
| Find the area of this shape: | Shape A = l x w = 5 x 3 = 15 Shape b = bh divided by 2 = 4 x 5 = 20/2 = 10 Total Area = 10 + 15 = 25m(squared) |
| Find the area of this shape: | Shape A = l x w = 10 x 3 = 30 Shape b = bh divided by 2 = 10 x 3 = 30/2 = 15 Total Area = 30 + 15 = 45km(squared) |
| Find the area of this shape: | Shape A = l x w = 7 x 6 = 42 Shape b = bh divided by 2 = 3 x 2 = 6/2 = 3 Total Area = 42 - 3 = 39m(squared) |
| Find the area of this shape: | Shape A = l x w = 20 x 20 = 400 Shape b = bh divided by 2 = 20 x 14 = 280/2 = 140 Total Area = 400 - 140 = 260cm(squared) |
| Find the length of the hypotenuse: | = 8.9 |
| Find the length of the hypotenuse: | = 13.03 |
| Find the length of the hypotenuse: | = 5.8 |
