# Cazoom Maths Teaching Resources: Full Protractor

## What is the resource?

This PDF has a printable protractor. It shows a full 360 degrees, unlike the simpler 'half' protractors used by younger learners. Best for secondary level maths.

## Why are protractors important?

Measuring angles is way more than just school lessons:

- Navigation: Sailors and pilots rely on accurate angles and similar tools.
- Engineering & design: From bridges to robots, machines involve carefully planned angles.
- 3D graphics: Even on screen, angles determine virtual object perspective.
- Scientific tools: Microscopes, telescopes – their lens angle determines magnification.

## Why is this resource helpful?

It supports accurate angle work and deeper understanding:

- Full 360 degrees: Measures even large or 'reflex' angles (over 180 degrees).
- Clear markings: Bold lines and readable scales make measuring precise.
- Printable PDF: Great when physical protractors are scarce or for test practice.
- Supports graphing: Essential for pie charts, circle geometry, and trigonometry.
- Develops technique: Teaches the correct placement and reading of a protractor.

This resource supports learners in moving beyond simply measuring angles. They use it to analyse shapes, graphs, and real-world situations.
