WebCircle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs. A circle is the locus of all points in a plane which are equidistant from a fixed point. The fixed point is called the centre of the … 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.

WebProving circle theorems Angle in a semicircle We want to prove that the angle subtended at the circumference by a semicircle is a right angle. Step 1: Create the problem Draw a circle, mark its centre and draw a diameter through the centre. Use the diameter to form one side of a triangle. The other two sides should meet at a vertex somewhere on the
