circle theorems
Understand the Problem
The question seems to be asking about circle theorems, which are principles in geometry concerning the properties and relationships of circles. This encompasses various theorems like the angle at the center, the angle at the circumference, and properties related to tangents and chords.
Answer
Circle theorems include angles inscribed in a circle, angles in the same segment, and right angles across a diameter.
Circle theorems include concepts like angles inscribed in a circle, angles in the same segment being equal, and angles across a circle's diameter being right angles.
Answer for screen readers
Circle theorems include concepts like angles inscribed in a circle, angles in the same segment being equal, and angles across a circle's diameter being right angles.
More Information
Circle theorems describe properties of circles linking angles, tangents, and chords. These theorems can be used to solve complex geometric problems involving circles.
Tips
A common mistake is confusing angles at the center with angles at the circumference, and forgetting that the angle in a semicircle is always 90 degrees.
