Master Geometry and get the right foundations for Year 9.

Year 8 Geometry is a core component of the Year 8 Measurement and Geometry strand. In this learning program students sort and classify triangles according to their sides or angles, identify convex and nonconvex shapes including quadrilaterals, and find unknown side lengths and angles. In addition, we work with students to recognise axes of symmetry, identify rotational symmetry and apply knowledge of sides and angles to prove shapes are congruent or similar.

Topics & Concepts We Cover

This learning program is made up of the following 3 topics, broken down into 22 concepts.

  • Properties of Triangles and Quadrilaterals 9 concepts

    1. Investigate the properties of special quadrilaterals (parallelograms, rectangles, rhombuses, squares, trapeziums and kites)

    2. Distinguish between convex and non-convex quadrilaterals

    3. Use the angle sum of a triangle to establish that the angle sum of a quadrilateral is 360 degrees

    4. Classify triangles according to side and angle properties

    5. Classify special quadrilaterals on the basis of their properties

    6. Use the angle sum of a quadrilateral property to find angles in a given diagram

    7. Investigate and apply the exterior angle of a triangle property to find angles in a given diagram

    8. Investigate and use the angle sum of a triangle property to find angles in a given diagram

    9. Find unknown sides and angles in a given diagram by using the properties of special triangles and quadrilaterals

  • Transformations in Geometry 8 concepts

    1. Plot and determine the coordinates resulting from rotating around the origin by a given number of degrees

    2. Draw a rotated image given an angle and direction

    3. Plot and determine the coordinates resulting from reflecting in either the x or y axis

    4. Identify congruent figures using transformations

    5. Plot and determine the coordinates resulting from translation

    6. Investigate axes of symmetry and the order of rotational symmetry of polygons, including circles and pictures

    7. Draw images using translation

    8. Draw a reflected image given a mirror line

  • Congruent Figures 5 concepts

    1. Name the matching sides and angles of congruent figures

    2. Investigate the minimum conditions needed for two triangles to be congruent

    3. Apply properties of congruent triangles to find an unknown angle or side, giving reasons

    4. Write formal proofs of congruence of triangles, preserving matching order of vertices

    5. Choosing a test for congruence (SSS test, SAS test, AAS test, RHS test)
