Overview

Year 10 Circle Geometry reveals important theorems about the circle and aligns with the Measurement and Geometry Strand of the Australian curriculum.  In this learning program, students develop an understanding of each circle theorem and confidently select and apply this theory to support geometrical proofs.

Topics & Concepts We Cover

This learning program is made up of the following 5 topics, broken down into 19 concepts.

  • Tangent and Secant Properties 7 concepts

    1. Tangents from an external point are equal.

    2. The angle between a tangent and a chord equals the angle at the circumference in the alternate segment

    3. The products of the intercepts of intersecting secants are equal

    4. The line joining the centers of two circles passes through their point of contact

    5. A radius (diameter) of a circle is perpendicular to the tangent at their point of contact

    6. The products of the intercepts of two intersecting chords are equal, and conversely

    7. The Tangent-Secant Theorem

  • Problems using Circle Theorems 2 concepts

    1. Apply tangent and secant properties of circles to find unknown angles and lengths

    2. Find unknown angles and lengths using chord and angle properties

  • Circle Definitions 1 concept

    1. Use terminology associated with angles in circles

  • Chord Properties 3 concepts

    1. When two circles intersect, the line joining their centres bisects their common chord at right angles

    2. A line through the centre of a circle perpendicular to a chord bisects the chord, and conversely

    3. Equal chords subtend equal angles at the centre and conversely

  • Angle Properties 6 concepts

    1. The angle at the circumference in a semi-circle is 90°, and conversely

    2. Equal arcs subtend equal angles at the circumference, and conversely

    3. The angle at the centre is twice the angle at the circumference standing on the same arc

    4. The opposite angles of a cyclic quadrilateral are supplementary, and conversely

    5. The exterior angle of a cyclic quadrilateral equals the interior opposite (or remote) angle, and conversely

    6. Proving Concyclicity
