Identify angles as measures of turn and use right angles as a reference to compare angles in everyday situations <ul> <li>using quarter, half and three-quarter turns and comparing them to a right angle, for example, a quarter turn is the same as a right angle; a half a turn is greater than a right angle and is the same as 2 right angles; a three-quarter turn is greater than a right angle and is the same as 3 right angles</li> <li>recognising that right angles occur at the corners of many everyday objects, for example, books, windows, tabletops and whiteboards</li> <li>identifying angles that are bigger than, smaller than and the same as a right angle in the environment; for example, opening doors partially and fully and comparing the angles created to a right angle</li> <li>exploring Aboriginal and/or Torres Strait Islander children’s instructive games to investigate angles as measures of turn, for example, in the game Waayin from the Datiwuy People in the northern part of the Northern Territory</li> </ul>

Remind your students about the most common types of angles with this set of six classroom posters.

What Are the Types of Angles?

When it comes to naming and classifying various angles, there is quite a lot for our students to remember! Not only do our students need to be familiar with the names of these common angle types, but they also need to understand the sizes and features of each. That’s where Teach Starter can help!

Display this set of six posters in your classroom when exploring angle types with your students. Each poster provides a simple explanation of each angle type, along with a visual representation to help students connect the description with a real example. The pack includes the following posters:

Angles (simple version) – Names and describes acute, right and obtuse angles.
Angles (advanced version) – Names and describes the size of acute, right, obtuse, straight, reflex and revolution angles.
Complementary and Supplementary Angles
Angles at a Point
Angle Sum of a Triangle
Angle Sum of a Quadrilateral

How to Make the Most of These Types of Angles Posters

These posters have been created to support you in teaching angle types to your students. You may wish to use them in the following ways:

Print each poster individually on A3 paper and display them in your classroom as a reminder of the various types of literary devices.
Print multiple posters to a page and provide them to the students to add to their workbooks. The page can then be continually referred to during your angles unit.
Project the posters onto your whiteboard. Cover up certain parts of the poster, then challenge students to add in the missing information.

Download, Print, Teach!

This poster pack downloads as a full-colour PDF. Just download, print and teach!
