1. The Angle at the Center Theorem

This theorem states that the angle formed at the center of a circle by two given points on the circumference is twice the angle formed at the circumference.all circle theorems assignment help It is particularly useful for solving problems involving inscribed angles.

Example

If an arc subtends a 60-degree angle at the circumference, then it will subtend a 120-degree angle at the center.

2. The Alternate Segment Theorem

This theorem states that the angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. It is particularly useful in proving angles in cyclic quadrilaterals.

Example

If a chord makes a 40-degree angle with a tangent at the point of contact, then the angle in the alternate segment will also be 40 degrees.

3. The Inscribed Angle Theorem

This theorem states that the angle subtended by a chord at the circumference is always the same, regardless of the position on the circle. This helps in identifying congruent angles within circle-related problems.

Example

If a chord subtends an angle of 50 degrees in one part of the circle, it will do the same in another segment.

4. The Perpendicular Bisector of a Chord

A perpendicular drawn from the center of a circle to a chord will bisect the chord. This theorem is particularly useful in proving congruency in geometric proofs.

Example

If a circle has a chord of 10 cm and a perpendicular is drawn from the center,Urgent Assignment Writing Help  it will divide the chord into two equal segments of 5 cm each.

5. The Tangent-Secant Theorem

This theorem states that if a tangent and a secant are drawn from a point outside a circle, the square of the length of the tangent segment is equal to the product of the secant segment’s external part and its whole length.

Example

If a tangent has a length of 6 cm and the external part of the secant is 4 cm, the full secant segment length will be 10 cm, satisfying the equation:

6. The Cyclic Quadrilateral Theorem

A quadrilateral that has all its vertices on the circumference of a circle is called a cyclic quadrilateral. The opposite angles in such a quadrilateral always add up to 180 degrees.

Example

If one angle in a cyclic quadrilateral is 70 degrees, the opposite angle will be: degrees.

7. The Equal Tangents Theorem

If two tangents are drawn to a circle from the same external point, their lengths are equal. This theorem is particularly useful in symmetry-based problems.

Example

If two tangents are drawn from a point P to a circle with lengths 8 cm each, then they are always equal regardless of their orientation.
