(Used for Tiffin Year 7 scheme of work) (a) Recognise notation to reference angles, triangles and sides. (b) Know the sum of the angles in a triangle, angles on a straight line and angles around a point. (c) Understand alternate, corresponding, cointerior and vertically opposite angles. Know that (interior) angles in a quadrilateral sum to 360. know angle properties of parallelograms. (d) Recognise that base angles of an isosceles triangle are equal. (e) Introduce and use algebraic angles. (f) Be able to construct diagrams from written information about vertices/sides/angles. (g) Construct angle proofs (including proving a triangle is isosceles, or two lengths are equal, or a line bisects an angle).
