Similar shapes have the same angles but different sizes. Students must identify similarity, use scale factors to find missing lengths, and at higher tier apply the square and cube relationships to areas and volumes.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Using the linear scale factor for area calculations instead of squaring it
Mixing up corresponding sides when setting up ratios
Confusing similar shapes (same shape, different size) with congruent shapes (identical)
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Transformations include translations, reflections, rotations and enlargements. Students must perform these on coordinate grids and describe transformations fully using correct mathematical language.
Geometry & MeasuresArea and perimeter calculations cover rectangles, triangles, parallelograms, trapezia and circles. Compound shapes combine these, and higher-tier questions involve sectors and segments of circles.
Geometry & MeasuresVolume and surface area questions range from simple prisms at foundation to cones, spheres and frustums at higher tier. Students must choose the correct formula, substitute values carefully, and give answers to appropriate accuracy.
