WebAdvanced General Maths - Cambridge WebCircle Theorems A circle is a set of points in a plane that are a given distance from a given point, called the center. The center is often used to name the circle. –T This circle shown is described an OT. As always, when we introduce a new topic we have to define the things we wish to talk about.

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 … WebThese are the circle theorems you need to know: Proof: Note: Once you have proved a theorem, you don’t need to prove it again if you need to use it to prove another theorem.
