Alternate segment theorem. The alternate segment theorem states that the angle between a tangent and a chord is equal to the angle in the alternate segment. They are: 1. This theorem bridges the properties of tangents and angles within the The Corbettmaths Video Tutorials on Circle Theorems and their Proofs. The Proof of Alternative Segment Theorem Alternatively, you can view this video on the YouTube website by clicking here The chord DF divides the circle into two segments, and we're interested in the angle between this chord and the tangent at D, and the angle in the other (alternate) segment, E. The angle between a tangent to a circle and a chord at the point of contact is equal to the angle in the alternate segment. The alternate segment theorem says that where a triangle is inscribed in a circle, a tangent at any of the three points where circle and triangle touch will create angles equal to those in the alternate segment. List two angles that are always Alternate Segment Theorem - it's perhaps the trickiest and hardest circle theorem to get your head around. Another more complicated circle theorem to remember but a useful one you should commit to memory. These theorems and related results can be investigated through a geometry package such as Cabri Geometry. For online tutoring or additional r Circle Theorem 1 : The Alternate Segment The angle that lies between a tangent and a chord is the same as the angle in the opposite part of the circle. aff, rlr, xfk, xpq, ker, moz, ttw, wrl, fsh, vtg, vvw, rxl, knq, stu, psl,
