Year 6 - Measurement and Geometry
Standard 6.MD.1.4 - Practice constructing obtuse, acute and right angles with a protractor.
Included Skills: Geometry
Geometric reasoning • 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 - identifying the size of a right angle as 90� and defining acute, obtuse, straight and reflex angles - measuring, estimating and comparing angles in degrees and classifying angles according to their sizes - investigating the use of rotation and symmetry in the diagrammatic representations of kinship relationships of Central and Western Desert people - recognising and using the two alternate conventions for naming angles
