ACMMG141: 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
Learning intentions:
- Understand the concepts of angles on a straight line, angles at a point, and vertically opposite angles.
- Understand how to use these concepts to find unknown angles.
- Understand the importance of using appropriate strategies and technologies to solve problems efficiently and effectively.
- Students can accurately investigate angles on a straight line, angles at a point, and vertically opposite angles.
- Students can use mental strategies, such as drawing a diagram and using angle relationships, to find unknown angles.
- Students can use appropriate digital technologies, such as a geometry app or a protractor, to measure and find unknown angles.
- Students can interpret the results of their work in the context of the problem and determine if the answer is reasonable.
- Students can explain their reasoning and solve problems involving the investigation and finding of unknown angles in a logical and organised way.
