**Using formulas to find angles in a circle StudyPug**

There are several ways of drawing an angle in a circle, and each has a special way of computing the size of that angle. Four different types of angles are: central, inscribed, interior, and exterior. Here, you see examples of these different types of angles. A central angle has its vertex at the... angle at the circumference subtended by the same arc, it can be seen that in a circle of diameter 1, the chord which subtends an angle at the circumference has length sin . This is well-deﬁned, since equal chords subtend equal angles.

- Chords of equal length in a circle subtend equal angles at the centre. 2. Chords of equal length in a circle are equidistant from the centre. 3. The perpendicular from the centre of a circle to a chord bisects the chord. 4. The line from the centre of a circle to the midpoint of the chord is perpendicular to the chord. 5. The perpendicular bisector of a chord of a circle passes through the

- 4. Equivalent angles in degrees and in radians We know that the arc length for a full circle is the same as its circumference, 2πr. We also know that the arc length = rθ.
