Year 7 - Measurement and Geometry
Standard 7.MD.1.4 - Practice identifying supplementary, complementary, vertical, and adjacent angles.
Included Skills: Geometry
Geometric reasoning • Identify corresponding, alternate and co-interior angles when two straight lines are crossed by a transversal - defining and classifying pairs of angles as complementary, supplementary, adjacent and vertically opposite • Investigate conditions for two lines to be parallel and solve simple numerical problems using reasoning - constructing parallel and perpendicular lines using their properties, a pair of compasses and a ruler, and dynamic geometry software - defining and identifying the relationships between altenate, corresponding and co-interior angles for a pair of parallel lines cut by a transversal • Demonstrate that the angle sum of a triangle is 180° and use this to find the angle sum of a quadrilateral - using concrete materials and digital technologies to investigate the angle sum of a triangle and quadrilateral • Classify triangles according to their side and angle properties and describe quadrilaterals - identifying side and angle properties of scalene, isosceles, right-angled and obtuse-angled triangles - describing squares, rectangles, rhombuses, parallelograms, kites and trapeziums
