Interactive geometry

When students can see geometry move, they stop guessing and start understanding.

Memorising angle rules does not produce understanding. SubjectMate pairs interactive geometry tools with guided AI tutoring so your child can construct shapes, drag points, and discover rules themselves.

a a b a = alternate angle a + b = 180° (co-interior) SubjectMate What is the relationship between angles a and b? They add up to 180 degrees! Correct. Co-interior angles are supplementary. Only true for parallel lines.
How it works

Constructed understanding, not memorised rules.

The interactive geometry canvas opens alongside the tutoring session. Your child does not just read about angle relationships, they construct them, drag them, and discover how they behave. SubjectMate guides them through each step with questions.

Live interactive geometry canvas

The geometry tool opens directly inside the session. Students construct triangles, circles, parallel lines, and any other figure while SubjectMate guides them through what to build and what to notice.

Guided discovery, not lectures

SubjectMate does not explain rules upfront. It asks your child to build a figure, drag a point, and observe what changes. When they describe what they see, SubjectMate names the theorem they just discovered.

Curriculum-matched topics

Every geometry topic is aligned to the Australian curriculum. SubjectMate knows which theorems are required at Year 8 versus Year 10, and what proof skills are expected in HSC, VCE, and QCE.

What is covered

Every geometry topic from Year 7 to Year 12

SubjectMate covers the full geometry progression from basic angle relationships through to circle theorems and formal proof.

01
Angles and parallel lines

Alternate, co-interior, corresponding angles. Students construct parallel lines and drag a transversal to see angle relationships hold.

02
Triangles and congruence

Angle sum, exterior angles, congruence conditions: SSS, SAS, AAS, RHS. Students construct triangles to understand when two must be identical.

03
Quadrilaterals and polygons

Properties of parallelograms, rectangles, rhombuses, and trapezoids. Angle sums discovered by constructing and subdividing shapes.

04
Circle theorems

Angle in a semicircle, angle at the centre, cyclic quadrilaterals, tangents, and chord properties. Each theorem discovered through construction.
