41s

Calculate angles using angle facts (including isosceles triangles) and provide full geometric arguments

41s Use the three-letter angle notation.

41s Angles in an isosceles triangle.

13s: Know there are 360⁰ in a full turn (180⁰ = half turn; 90⁰ = quarter turn) and recognising types of angle: acute, obtuse, reflex or right

26s: Use the sum of angles at a point or on a line or vertically opposite to calculate angles

32s: Know and use the sum of angles in a triangle or quadrilateral to work out angles
