1. 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.

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.
