Bearings What are bearings? Bearings are a way of describing and using directions as angles They are specifically defined for use in navigation because they give a precise location and/or direction...
Sine Rule What is the sine rule? The sine rule allows us to find missing side lengths or angles in non-right-angled triangles It states that for any triangle with angles A, B and C Where a is the s...
Pythagoras What is the Pythagorean theorem? Pythagoras’ theorem is a formula that works for right-angled triangles only It states that for any right-angled triangle, the square of the hypotenuse is...
Volume of 3D Shapes What is volume? The volume of a 3D shape is a measure of how much 3D space it takes up A 3D shape is also called a solid You need to be able to calculate the volume of a number ...
3D Coordinate Geometry How does the 3D coordinate system work? In three-dimensional space we can label where any object is using the x-y-z coordinate system In the 3D cartesian system, the x- and y...
Length of an Arc What is an arc? An arc is a part of the circumference of a circle It is easiest to think of it as the crust of a single slice of pizza The length of an arc depends of the size of t...
Radian Measure What are radians? Radians are an alternative to degrees for measuring angles 1 radian is the angle in a sector of radius 1 and arc length 1 A circle with radius 1 is called a unit ci...
Basic Coordinate Geometry What are cartesian coordinates? Cartesian coordinates are basically the x-y coordinate system They allow us to label where things are in a two-dimensional plane In the 2D ...
