Involves an x3 (cubic) and 1/x (reciprocal)

Transformations and Constructions

Overview

– 3D solids

– Reflection and rotation

– Translation and enlargement (To include computer generated imagery and vectors)

– Combinations of transformations

– Bearings and scale drawings

– Constructions

– Loci

Example Key Words

## Transformation

A change in the position, size or shape of a figure

## Bearing

Measuring the angle from one postion to another. Written as a 3 digit number, measured from the north line, in a clockwise direction.

## Scale Drawing

A drawing that shows a real object with accurate sizes in proportion to the reduced or enlarged by a certain amount (called the scale)

## Construction

Turning a shape around a fixed point.

## Loci

This changes the size of the shape – it can make it smaller.

## Scale factor

A drawing which has been reduced or enlarged from its original size, to a specified scale

Probability

Overview

– Combined events

– Mutually exclusive events

– Experimental probability

– Independent events and tree diagrams

– Conditional probability

– Venn diagrams and set notation

Example Key Words

## Probability

The likelihood or chance of a given event happening. Often expressed as a fraction, decimal or percentage.

## Experimental probability

A calculation obtained from an experiment.

## Venn diagram

A diagram that represents sets and shows where those sets intersect.

## Probability tree diagram

A tree diagram is used to determine and visualise all the outcomes and probabilities of 2 or more events

## Mutually exclusive

A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes

## Independent events

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.

Similarity and Congruence

Overview

– Congruence

– Geometric proof and congruence

– Similarity

– Similarity in 3D solids

Example Key Words

## Congruent

Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.

## Similar

Two shapes are said to be similar if they are exactly the same shape, but are different in size. All sides are in the same proportion defined by the scale factor.

## Similarity in area and volume

If 2 shapes are similar and the scale factor of the lengths is x, then the scale factor of the area is x2 and the scale factor iof the volume is x3

Algebra

Overview

– Algebraic indices

– Expanding and factorising

– Equations

– Formulae

– Linear sequences

– Non-linear sequences

Example Key Words

## Expanding brackets or multiplying out brackets

This involves mulitplying each term inside the bracket by the number/letter outside the bracket or inside a second bracket

## Factorising

The opposite of multiplying out brackets, involves putting the expression into bracket(s)

## Formula

An equation that expresses a mathematical relationship between two or more variables

## Term of a sequence

A number in a sequence

## Linear sequences

The term to term rule is a constant number and the nth term rule just involves “n”

## Non- linear sequence

Generally a quadratic sequence where you need to find the 2nd difference and the nth term rule will involve “n2”

Angles and Trigonometry

Overview

– Angle properties of triangles, quadrilaterals and parallel lines

– Interior angles of a polygon

– Exterior angles of a polygon

– Pythagoras’ theorem

– Trigonometry

Example Key Words

## Hypotenuse

The longest side of a triangle. It is also the side opposite the right angle.

## Pythagoras' Theorem

A theorem stating that in a right triangle the area of the square on the hypotenuse is equal to the sum of the areas of the squares drawn on the other two sides.

## Opposite and adjacent side Side

The side opposite (opposite) and next to (adjacent) the angle you are dealing with in a triangle (not the right angle)

## The Sine ratio

The sine of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to that of the hypotenuse.

## The Cosine ratio

The cosine of an angle in a right triangle is defined as the ratio of the length of the side adjacent to the angle to that of the hypotenuse.

## The Tangent ratio

The tangent of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to that of the adjacent side.
