WebTheorem 4: Two equal chords subtend equal angles at the center of the circle. Proof: Consider a circle given below with center O and two chords AB and CD such that AB = CD. Now, we need to prove ∠AOB = ∠COD. … WebYou may have to be able to prove the alternate segment theorem: We use facts about related angles. A tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The … Tangent: A tangent to a circle is a straight line which touches the circle at only one …
