Working together to improve teaching & learning Leagan Gaeilge

Pupils will be presented with 2 parallel lines and 5 points (A, B, C, D and E). Angle ABC is 110 ̊ and
CDE is 50 ̊. Pupils must find the measure of angle BCD, they can do this by creating exterior angles,
right angles, triangles, vertically opposite angles and alternate angles and applying properties of these
to find the angle.
