![]() ![]() Use the basic congruence criteria for triangles (SSS, SAS, ASA, RHS)Īpply angle facts, triangle congruence, similarity and properties of quadrilaterals to conjecture and derive results about angles and sides, including Pythagoras’ theorem and the fact that the base angles of an isosceles triangle are equal, and use known results to obtain simple proofs Including knowing names and using the polygons: pentagon, hexagon, octagon and decagon. Notes: including knowing names and properties of isosceles, equilateral, scalene, right-angled, acute-angled, obtuse-angled triangles. G4ĭerive and apply the properties and definitions of: special types of quadrilaterals, including square, rectangle, parallelogram, trapezium, kite and rhombusĪnd triangles and other plane figures using appropriate language Notes: colloquial terms such as Z angles are not acceptable and should not be used. Understand and use alternate and corresponding angles on parallel linesĭerive and use the sum of angles in a triangle (eg to deduce and use the angle sum in any polygon, and to derive properties of regular polygons) G3Īpply the properties of angles at a point, angles at a point on a straight line, vertically opposite angles Notes: including constructing an angle of 60°. Know that the perpendicular distance from a point to a line is the shortest distance to the line Use these to construct given figures and solve loci problems Use the standard ruler and compass constructions (perpendicular bisector of a line segment, constructing a perpendicular to a given line from/at a given point, bisecting a given angle) Use the standard conventions for labelling and referring to the sides and angles of triangles ![]() Use conventional terms and notations: points, lines, vertices, edges, planes, parallel lines, perpendicular lines, right angles, polygons, regular polygons and polygons with reflection and/or rotation symmetries ![]() Published 12 September 2014 | PDF | 807.4 KB 3.4 Geometry and measures 3.4.1 Properties and constructions G1 ![]()
