In this practical task, students use models of 3-dimensional shapes to complete a chart showing the number of faces, corners, and edges for each object.
Students are required to draw in arrows to show the parallel lines on three given shapes. They then draw in a right-angle symbol to show the perpendicular lines on three other given shapes.
Students draw diagrams to demonstrate their understanding of three angle properties: angles at a point, adjacent angles on a straight line and vertically opposite angles.
Students use their knowledge of angle properties of parallel lines and angles on a straight line to identify similar angles and to calculate the sum of three angles giving appropriate explanations.
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 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.
