Standard

What is the 7th circle theorem?

Specifically, given a chain of six circles all tangent to a seventh circle and each tangent to its two neighbors, the three lines drawn between opposite pairs of the points of tangency on the seventh circle all pass through the same point.

How many circle theorems are there GCSE?

seven circle theorems
Circles have different angle properties, described by theorems . There are seven circle theorems. An important word that is used in circle theorems is subtend .

    Circle Theorems and Proofs

    • Theorem 1: “Two equal chords of a circle subtend equal angles at the centre of the circle.
    • Theorem 2: “The perpendicular to a chord bisects the chord if drawn from the centre of the circle.”
    • Theorem 3: “Equal chords of a circle are equidistant (equal distance) from the centre of the circle.”

    What are the 7 circles?

    What are the 9 circle theorems?

    Now for the theorems:

    • The angle at the centre is twice the angle at the circumference.
    • The angle in a semicircle is a right angle.
    • Angles in the same segment are equal.
    • Opposite angles in a cyclic quadrilateral sum to 180°
    • The angle between the chord and the tangent is equal to the angle in the alternate segment.

    How many theorems are there in circles Class 9?

    Theorem 1: Equal chords of a circle subtend equal angles at the centre. Theorem 2 : If the angles subtended by the chords of a circle at the centre are equal, then the chords are equal. Theorem 3 : The perpendicular from the centre of a circle to a chord bisects the chord.

    How many theorems are in the circle class 10?

    Thus, the two important theorems in Class 10 Maths Chapter 10 Circles are: Theorem 10.1: The tangent at any point of a circle is perpendicular to the radius through the point of contact. Theorem 10.2: The lengths of tangents drawn from an external point to a circle are equal.
