Students use the angle between a tangent and a radius property and the base angles in an isosceles triangle property to find an unknown angle and to explain why line segments are of equal size.
Students use their knowledge of the angle between a tangent and radius property and the sum of the angles in a quadrilateral to work out unknown angles in a diagram and explain their workings.
Students write short paragraphs using geometrical terms to describe two pictures. The terms equilateral, scalene, and isosceles are to be used to describe a castle. The words circumference, diameter, and radius are to be used to describe a bicycle.
Students calculate the size of marked angles using their knowledge of angle properties: the angle between a tangent and a radius, the sum of angles in a triangle and the sum of angles in a quadrilateral.
Students calculate the lengths of circles and straight lines on an oval athletics track from its given radius and total length, and show their working.
