WebThe seven circle theorems are as follows: The angle at the center is twice the angle at the circumference of a circle. Angles in a semicircle is 90 °. Angles in the same segment are equal. In a cyclic quadrilateral, the sum of opposite angles is 180 °. WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that.

WebAccording to the angle sum property of triangle theorem, the sum of all angles of a triangle = 180° In ΔAOB, ∠OAB + ∠AOB +∠OBA = 180° ∠OAB + 90° + ∠OAB = 180° 2∠OAB = 180° – 90° 2∠OAB = 90° ⇒ ∠OAB = 45° Now, in ΔAOC, OA = OC (radius of the circle) As mentioned above, angles opposite to equal sides are equal. ∴ ∠OCA = ∠OAC WebIn geometry, Thales's theorem states that if A, B, and C are distinct points on a circle where the line AC is a diameter, the angle ∠ ABC is a right angle.Thales's theorem is a special case of the inscribed angle theorem and is mentioned and proved as part of the 31st proposition in the third book of Euclid's Elements.

WebExample 2: Find the missing angle x° using the intersecting secants theorem of a circle, given arc QS = 75° and arc PR= x°. Solution: Using the secant of a circle formula (intersecting secants theorem), we know that the angle formed between 2 secants = (1/2) (major arc + minor arc) 45° = 1/2 (75° + x°) 75° + x° = 90°.
