Geometry Cumulative Assessment 2 & Key

Master higher-tier polygon angles, advanced coordinate geometry, circles and cylinders, area-scale factor relationships for enlargements, and multi-stage transformations (rotations and translations) with this challenging cumulative assessment worksheet! Following on from the first geometry assessment, this 50-mark resource tests rigorous spatial reasoning and geometric proof without relying on a calculator.

What is Included:

Section A: Short Answer
Evaluates harder core geometric facts. This includes finding the sum of interior angles and individual interior angles of regular polygons, determining the number of sides of a regular polygon from its exterior angle, calculating the area of a trapezium, and finding the area of a coordinate triangle defined by vertex coordinates.

Section B: Angles, Circles and Solids
Focuses on executing standard higher-tier procedures involving parallel line angle reasoning, circle circumference and area calculations using exact pi terms, cylinder volume and surface area evaluations, and complex pool-filling rate problems linking cubic meters to litres and minutes.

Section C: Mensuration and Transformations
Guides students through intensive measurement and multi-stage transformation tasks. Challenges involve determining side lengths of squares from area values, analyzing how area scales with linear scale factors for enlargements, and tracking coordinate vertices through a 90-degree anticlockwise rotation followed by a vector translation while verifying congruence.

Section D: Reasoning
Requires students to provide clear, written geometric justifications and angle proofs. Topics include analyzing composite shapes formed by regular polygons sharing edges (such as a pentagon and a square) and calculating remaining interior or exterior angles at shared vertices with full mathematical reasoning.
