DEVELOPMENT Mins Ask learners to draw the following: angles on a straight line perpendicular lines intersecting lines and parallel lines cut by a transversal. Ask the learners to identify any difference in the lines they have drawn. Ask the learners to draw quadrilaterals. Give their properties. Work through different problems starting with problems that will help learners understand the concept, e.g. Solve problems of line and perpendicular on a straight line and highlight to the learners the properties of angles on a straight line. Next, show learners the difference between parallel lines and intersecting lines. Solve problems on parallel lines and learners observe the problem-solving strategy. Do the same with intersecting lines, and again, learners observe the problem-solving strategy. Solve problems that require application of properties of quadrilateral. Introduce problems with algebra and help the learner solve and make substitutions in an expression to determine the angles. 1. Fill in the sizes of the marked angles on the diagram. Make sure you give reasons for your answer. (4)
