Understanding Circle Theorems

Circles are fascinating shapes with intriguing properties. Understanding circle theorems can unlock the mysteries of circular motion and aid in problem-solving in geometry. Here's a brief overview:

• The Angle at the Centre Theorem: The angle subtended at the center of a circle is twice the angle subtended at the circumference.
• The Inscribed Angle Theorem: An inscribed angle is half of the central angle that subtends the same arc.
• Tangents and Radii: A tangent to a circle is perpendicular to the radius at the point of contact.
• Cyclic Quadrilateral: Opposite angles in a cyclic quadrilateral sum to 180°.

Here's a little froge tip: Always draw a diagram when dealing with circle theorems! It helps visualize relationships and solve problems more effectively.
