Quadrilaterals
The different types of quadrilateral are illustrated in the first seven interactive sheets of this excel file. Examples of each type of quadrilateral are shown and then further examples illustrated on a coordinate grid. The next sheet is more like a quiz as...
Prisms
This interactive excel file shows how the volume of a prism relates to the area of cross section and the length. Various different shapes of cross section are used including pentagons, hexagons, circles and semicircles. In each interactive sheet the cross section can be...
Similarity
The first five interactive sheets deal with various types of diagram involving similar triangles. Each sheet shows a clear diagram and a table of values. Lengths of line segments can be revealed to allow the student to calculate the scale factor of enlargement and the...
Tetrahedron
This interactive file deals with various angles and lengths within tetrahedrons.
The first sheet shows the diagram of a regular tetrahedron. Various sides and angles need to be calculated using Pythagoras Theorem and...
