Trigonometry, made visual and practical
Learn indoors.Explore outdoors.
Build understanding with Trig Lab, then extend the lesson with the Clinometer when a real-world activity fits your teaching.
Trig Lab · Feature 01
Connect the diagram to the decision. Students identify the relevant sides and recognise the matching TOA · CAH · SOH relationship.
Start by looking at what is given and what you need to find.
Trig Lab · Feature 02
Make the thought process visible. The optional Computational Thinking Lens helps students break a problem down, focus on what matters, recognise a useful pattern and organise a repeatable solving approach.
Break the problem into smaller decisions before calculating.
Work through smaller decisions.
Keep only what matters.
A and H connect to CAH.
Put the solving sequence in order.
Trig Lab · Feature 03
Turn a real image into a trig problem. Add a suitable photograph, build the triangle, place the known information and let students work through the solution step by step.

Clinometer · Feature 01
You design the activity. Clinometer provides the measurement tool. Use the buildings, trees, flagpoles or other suitable objects around you to create activities that fit your students and your surroundings.
Stand 18 m from the building. Measure the angle of elevation to the top, then use trigonometry to estimate its height.
Different surroundings can inspire different activities. The teacher decides the task.
Different surroundings. Different activities. One Clinometer supports the activity you choose to design.
Clinometer · Feature 02
Use the Angle Explorer to see acute, right and obtuse angles change as the ray rotates. At 90°, the right-angle relationship locks into place.
