WebCircle theorems are properties that show relationships between angles within the geometry of a circle. We can use these theorems along with prior knowledge of other angle properties to calculate missing angles, … WebThe first circle theorem we’re going to use here is: Rule 3, the angle at the centre is twice the angle at the circumference. The angle at the centre is 126\degree 126°, so; \angle BAD = 126\degree \div 2 = 63\degree ∠B AD = 126° ÷ 2 = 63°. We now know two out of the four angles inside ABCD AB C D.
