Topics & Concepts We Cover

This learning program is made up of the following 4 topics, broken down into 21 concepts.

  • Angle relationships 4 concepts

    1. Apply rule that if two lines are parallel to a third line then they are parallel to one another

    2. Use angle relationships to identify parallel lines

    3. Find angles at a point using angle relationships

    4. Use angle relationships of parallel lines to find the size of unknown angles, giving reasons

  • Angles of Polygons 6 concepts

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

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

    3. Apply Exterior Angle Sum of Polygons

    4. Apply the Interior Angle Sum of a Polygon formula

    5. Apply the triangle inequality rule

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

  • Congruence and Similarity 9 concepts

    1. Apply the intercepts and parallel lines properties to find unknown sides

    2. Application of congruent triangles to prove properties of special triangles and quadrilaterals

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

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

    5. Scaling ratio for volume
