Circle Theorem's Flash Cards
Karten in diesem Stapel (6)
- 1—Arrow Theorem:
'the angle subtended from the circumference is half the angle subtended from the centre' - 2Describe this theorem. There are two!1. where the radius and tangent meet, the angle is always 90 degrees. (Angles A and C)
2. two tangents drawn from the same point are the same length (point B)
- 3describe the 'bow tie' theoryangles subtended from the circumference sharing the same arc are equal
(or)
angles in the same segment are equal
- 4in an exam, what would you say to describe the cyclical quadrilateral theory.opposite angles in a cyclical quadrilateral are supplementary (they add to 180 e.g. a+c=180 and b+d=180)
- 5describe the circlethe angle subtended on the diameter of a circle is always a right-angle (E=90 degrees).
the line from the centre that meets the centre of the chord always meets at 90 degrees (angle M)
- 6what would you say in an exam about the alternate segment theoryAlternate segment theory (angle at the tangent line is the same at the angle opposite)
