This chapter
Triangles & circles
| Angle sum of triangle | 180 degrees |
|---|---|
| Pythagoras | hypotenuse^2 = base^2 + height^2 |
| Area of triangle | (1/2) x base x height; Heron: root(s(s-a)(s-b)(s-c)) |
| Angle in semicircle | 90 degrees |
| Exterior angle | equals sum of opposite interior angles |
Mensuration
| Circle | area = pi r^2, circumference = 2 pi r |
|---|---|
| Rectangle / Square | lb ; side^2 |
| Cuboid volume / Cube | l x b x h ; a^3 |
| Cylinder | volume pi r^2 h, curved surface 2 pi r h |
| Cone / Sphere | (1/3) pi r^2 h ; (4/3) pi r^3 |
