| Question | Answer |
| Pythagoras Therum What is it? | Triangles Angles (right) Hypotenuse (long side of triangle) A+B=C |
| Triangle names | Scalene = all angles are different Isosceles = 2 sides the same Equilateral = All sides equal |
| Finding the Hypotenuse (Long side of triangle) | |
| Finding the opposite (short side of triangle) | |
| Sides of triangle | |
| Pythagoras therum with 3D shapes | |
| Trigonometry What is it? | SOH CAH TOA silly old Hagrid caught a hippogriff trotting over apples |
| Finding the side lengths (on top) | When the unknown is on the top we multiply |
| Finding side lengths (unknown on bottom) | When unknown is on bottom we divide |
| Angles | Acute = 0 to 90 degrees Obtuse = 90 to 180 degrees Reflex = 180 to 360 degrees Right angle 90 degrees |
| Finding angles | With calculator= shift, tan-1 ( - ) = |
| Angle of elevation and depression | Elevation = angle above the horizontal line Depression = angle below the horizontal line |
| Working out angles of elevation | |
| Work out of depression | |
| Substitute values into equations | |
| Meanings of these algebraic expressions | Sum = + difference = - product (multiplied) = x quotation = divide |
| Create algebraic expressions (examples) | the sum of a number and 7 = n+7 the difference between 9 and a number = 9-n the product (x) of a number and 4= n x n=4 |
| Solving linear equations graphically and algebraically | |
| Finding the distance between 2 points on the Cartesian plane | |
| Graphing linear in equations |
