WebWe start by saying that the angle subtended by arc CD at O is 2θ and the arc subtended by arc AB at O is 2Φ. By the Angle at the Center Theorem: ∠DAC = ∠DBC = θ and ∠ADB = ∠ACB = Φ. And PAC is 180°, so: ∠DAP … WebJan 26, 2024 · Subtract the known interior angle from the exterior angle: \angle J-\angle F=\angle G ∠J − ∠F = ∠G. Suppose an exterior angle measures 110° and you are told one of its opposite interior angles measures 47°. Plug in the knowns to find the unknown: 110°−47°=63° 110° − 47° = 63°.

WebTheorem: The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle’s circumference. The proof of this theorem is quite simple, and uses the exterior angle theorem – an exterior angle of a triangle is equal to the sum of the opposite interior angles. If the two opposite interior angles ...
