## Happy Trails 1 The Hunt for Angles

#### Activity Overview

In this activity students use their local environment as a source of Mathematical inspiration. They capture digital images to demonstrate their understanding of the follow types of angles:
Acute, Right, Obtuse, Straight and Reflex

#### Objectives

Australian Curriculum references
Compare angles and classify them as equal to, greater than or less than a right angle (ACMMG089)
Investigate, with and without digital technologies, angles on a straight line, angles at a point and vertically opposite angles. Use results to find unknown angles (ACMMG141)
Estimate, measure and compare angles using degrees. Construct angles using a protractor (ACMMG112)

acute angle
right angle
obtuse angle
