Vocabulary And Properties Of Circles
Gbogbo ọrọ náà
A circle has its own vocabulary: radius, diameter, chord, tangent, arc, sector and segment. Knowing exactly what each word means, and the key property that a tangent meets the radius at a right angle, turns circle problems from confusing to routine.
In this lesson you will learn the parts of a circle and the most useful property for problem solving: a tangent is perpendicular to the radius at the point where they touch. That single right angle is the key to a whole family of exam questions.

- Use the vocabulary and properties of circles, including that a tangent is perpendicular to the radius at the point of contact.
