Area and perimeter calculations cover rectangles, triangles, parallelograms, trapezia and circles. Compound shapes combine these, and higher-tier questions involve sectors and segments of circles.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Using the slant height instead of the perpendicular height for triangle area
Confusing the formulas for area and circumference of a circle
Forgetting to halve when using the triangle area formula
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Volume 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.
Geometry & MeasuresCircle theorems are a higher-tier geometry topic that often carries significant marks. Students must identify and apply theorems about angles in circles, tangents, chords and cyclic quadrilaterals, always giving geometric reasons.
Geometry & MeasuresTrigonometry uses sine, cosine and tangent ratios to find missing sides and angles in right-angled triangles. Higher-tier students extend this to non-right-angled triangles using the sine rule, cosine rule, and area formula.
