Year 7 - Measurement and Geometry

Standard 7.MD.1.4 - Practice identifying supplementary, complementary, vertical, and adjacent angles.

Included Skills:

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
