Geometric skills
Perimeter and area
The perimeter and area of triangles, quadrilaterals (rectangle, parallelogram, rhombus, kite and square), circles, arcs, sectors and composite shapes can all be calculated using relevant formulae.
Volume
Using relevant formulae the volume and surface area of cuboids, cubes, prisms, cylinders, spheres, cones and composite shapes can be calculated.
Pythagoras
Pythagoras' Theorem can be used to calculate the length of the third side of a right angled triangle when given the lengths of the other two sides.
Gradient of a slope
Gradient is a measure of how steep a slope or a line is. Gradients can be calculated by dividing the vertical height by the horizontal distance.
