Angle Facts – Foundation – GCSE Questions These questions are the same format as previous GCSE exams. COPY means they use the exact same numbers as the original GCSE question. Otherwise, they are clone questions using different numbers. The worksheets are provided in a variety of sizes.

Printing To print handouts from slides - Select the slide from the left. Then click: File > Print > ‘Print Current Slide’ To print multiple slides - Click on a section title to highlight all those slides, or press ‘Ctrl’ at the same time as selecting slides to highlight more than one. Then click: File > Print > ‘Print Selection’ To print double-sided handouts - Highlight both slides before using ‘Print Selection’. Choose ‘Print on Both Sides’ and ‘Flip on Short Edge’.

Triangle ABC is isosceles because GCSE Edexcel Foundation: November 2017 Paper 3, Q7 1 D C 123° 57° 57° 66° A B BCD is a straight line. ABC is a triangle. Show that triangle ABC is an isosceles triangle. Give a reason for each stage of your working. Angle ACB = 180 – 123 = 57° (Angles on a straight line add to 180°) Angle ABC = 180 – 57 – 66 = 57° (Angles in a triangle add to 180°) Triangle ABC is isosceles because two angles are equal.
