Official Curriculum Content Description:

establish properties of quadrilaterals using congruent triangles and angle properties, and solve related problems explaining reasoning

Worked Examples (2)

Example 1Classifying Quadrilaterals & Properties
Is every parallelogram also classified as trapezium?
Diagram not accurately drawn
Common mistake: Matched the shape by its appearance rather than its counted properties
Correct Answer:no
Worked Solution:
A parallelogram is not always a trapezium.
Example 2Interior Angle Sum of Polygons
Each exterior angle of a regular hexagon is 60°. What is the size of each interior angle?
Diagram not accurately drawn
Common mistake: Subtracted from 360° instead of 180°
Correct Answer:120°120°
Accepted: A unit is optional (degrees, deg, ° all accepted).
Worked Solution:
Interior and exterior angles add up to 180°: 180∘−60∘=120∘180^\circ - 60^\circ = 120^\circ.
