## Bearings

Bearings work by giving you a set number of degrees to turn clockwise from North.They should always be given as three full digits (plus any decimal places) with...

## Loci and Constructions

A locus is just a line or region that shows all the points that fit a given rule. There's a few types.Loci That Are Fixed Distances From A Given PointIf somethi...

## Triangle Construction

There are a couple of techniques you might be expected to know for drawing a proper good triangle. Drawing A Triangle If You Have 3 SidesExample: Draw the tr...

## Unit Conversions

Just some handy conversions. You're expected to know the metric ones, not the imperial ones...but they can come in handy. Metric1cm = 10mm1m = 100cm1km = 100...

## Distance-Time Graphs

You might get given a distance-time graph in the exam...but don't worry they are pretty easy.At any point the gradient is the speed. So the steeper the graph th...

## Density And Speed

These two are easy to work out if you remember the triangle trick: DensityDensity is mass per unit volume. It is written, for example, like this g/cm3.Densit...

## Volumes

## Surface Area

If dealing with 3D shapes you might be asked to find the surface area of a shape. One way may be to look at its net. Nets A net is just a 3D shape folded ...

## Areas

## Projections

These are just different views of a 3D shape. There's three different types - front elevations, side elevations and plans.These are big names for something quit...
