| Define "Reflection" | Object and Images are the same distance from the line of symmetry (Mirror Line). If you joined an object point and its image point it would cross the mirror line at 90 degrees. |
| Define "Rotation" | The action of rotating around an axis or center. |
| Define "Rotational Symmetry" | This state how many times a shape like itself in one full turn. |
| Define "Enlargement" | Enlargement makes a shape bigger (or smaller) depending on the scale factor. A scale factor of 3 means the new shape will me 3 times as big as the original. A scale factor of 1/2 means it will be half the size. |
| What is a "Line Graph"? | When a line is given to us in the form of an equation "y-mx+c" |
| What does the coefficient of "x" mean? | The coefficient of x if the gradient/steepness. |
| Define "Translation" | A move in an object from one place to another. Usually we use a "Vector of Translation". Negative means left and positive means right on the top. Negative means down and positive means up on the bottom. |
| What is the order of operations? | It is the order in which you solve a problem. Parentheses first, Exponents and Roots next, Multiplication and Division and Addition and Subtraction last. |
| What are reciprocals | Reciprocals are the invert of the fraction. |
| What is the top and the bottom of a fraction called? | Numerator and Denominator |
| How do you increase and decrease percentages? | To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease. |
| If you add up all the interior degrees in a quadrilateral, what does it add up to? | 360 degrees |
| If you add up all the interior degrees in a triangle, what does it add up to? | 180 degrees? |
| If you add up all the interior degrees in a pentagon, hexagon, decagon, what does it add up to | 540 degrees, 720 degrees, 1440 degrees. |
| Define "Ratios" | he quantitative relation between two amounts showing the number of times one value contains or is contained within the other |
| What are the 4 types of angles in parallel lines? | Interior, Alternate and Corresponding and Vertically Opposite Angles (VOA) |
| How do you simplify ratios | The same way as you would do with fractions. 1/3 is the same as 2/6. Just as 1:3 and 2:6. |
| How do you find the area of a 3D shapes | Find the area of the face of the shape and stretch it across the shape. |
| How do you find the are of a circle? | πr2 |
| How do you find the circumference of a circle? | 2πr |
| What is the formula to find the area of a triangle? | b × h × ½ |
| What is the formula to find the area of a square | b × h |
| What is the formula to find the area of a trapezoid? | (a + b × 1/2) × d |
| What is the formula to find the area of a parallelogram? | b × h |
| What are the properties of interior angles. | They add up to 180 degrees. |
| What are the properties of Corresponding Angles. | They have the same degrees. |
| What are the properties of Vertically Opposite Angles | They are vertically opposite from each other. |
| What are the properties of Alternate angles | They have the same degrees. |
| Factorise 4j3+8j2+7j+14 | (4j2+7)(j+2) |
| Factorise 6x + 24 | 6(x +4) |
| Factorise 8x²− 8x | 4x(2x-2) |
| Factorise 6x² + 8x + 12yx | 2x(3x + 4 + 6y) |
| Multiply out 3n(5n + 7) | 15n² + 21n |
| Multiply out 3x(5x + 5a) | 15x² + 15ax |
| Multiply out 15ax(1ax + 5x) | 15a²x² + 75x² |
