Circle Theorems
Fichas del conjunto (10)
- 1—The line from the centre to the midpoint of a chord will cut the cord at right angles.
- 2—The radius and the tangent meet at right angles.
- 3—Two intersecting tangents to a circle are equal in length.
- 4—The angle at the centre is twice the angle at the circumference.
- 5—Angle subtended by the same cord (in the same segment of the circle) are equal.
- 6—The angle subtended from the diameter is always at a right angle.
- 7—Opposite angles in a cyclical quadrilateral add up to 180 degrees.
- 8—Alternate segment theorem.
the angle between the cord and the tangent is equal to the angle subtended from the same cord in the opposite segment.
- 9—Intersecting Cords (internal)
AX x BX = CX x DX
X is the point of intersection
- 10—Intersecting chords (external)
AX x BX = CX x DX
X is the point of intersection
