2 STARTER Creative Entrepreneur Responsible Citizen Independent Learner Positive Thinker Team Worker Reflective Learner Enterprise Skills Which ones are you using? EXTENSION TASK 1) Work out the missing angles below: 1) 20° b c 2) d 35° Vertically opposite angles are equal 20° Angles on a straight line add to 180° 160° Angles on a straight line add to 180° 145° 3) 135° 115° f Angles around point add to 360° 110° 4) 110° 85° 80° i Angles in a quadrilateral add to 360° 85° Work out the missing angles below: g h 30° 73° Angles in a triangle add to 180° 77° Angles on a straight line add to 180° 103° 2) 44° 82° j k Vertically opposite angles are equal 44° 90° Angles in a quadrilateral add to 360° 144°

3 INTRODUCTION Creative Entrepreneur Responsible Citizen Independent Learner Positive Thinker Team Worker Reflective Learner Enterprise Skills Which ones are you using? Parallel Lines Lines which are an equal distance apart and never meet. Arrows move in the same direction. These lines are parallel This line is called a transversal

4 INTRODUCTION Creative Entrepreneur Responsible Citizen Independent Learner Positive Thinker Team Worker Reflective Learner Enterprise Skills Which ones are you using? TASK – INVESTIGATION In groups, discuss and find connections between the different angles below as positive thinkers and creative entrepreneurs. a b c d e f g h Apart from vertically opposite angles being equal, angles on a straight line adding to 180° and angles around a point adding to 360°, you also need to learn that alternate angles are the same and corresponding angles are the same c = f because of alternate angles (Z-shaped) d = e because of alternate angles (Z-shaped)
