Segment: A part of the circle separated from the rest of a circle by a chord. We are no longer forming a linear expression and equating it to an angle fact like 180 o. Tangents and Normal to a Curve A tangent is a line that touches a curve. The degree of angles will be the same. This theorem states that A×B is always equal to C×D no matter where the chords are. A tangent meets or touches a circle only at one point, whereas the tangent line can meet a curve at more than one point, as the diagrams below illustrate. Candidates are required to answer ALL questions. Circle Theorems - angles on the same arc. Proving circle theorems Angle in a semicircle We want to prove that the angle subtended at the circumference by a semicircle is a right angle.
