Investigate, with and without the use of digital technologies, angles on a straight line, angles at a point, and vertically opposite angles; use the results to find unknown angles (ACMMG141)
Outcomes
-
Identify and name angle types formed by the intersection of straight lines, including right angles, 'angles on a straight line', 'angles at a point' that form an angle of revolution, and 'vertically opposite angles'
Examples
-
Investigate, with and without the use of digital technologies, angles at a point and establish that they form an angle of revolution and add to 360 degrees
