Question

What are the properties of a circle?

Answer 1

Properties of a circle:

A circle is a closed shape created by tracing a point moving on a plane at a constant distance from another point.

A circle's properties are following.

• A chord is a line segment with endpoints on the circle's circumference.

• A perpendicular, dropped from the center, divides a chord into two equal parts.
• A tangent is a line that touches the circle at any one point. The radius is always perpendicular to the tangent at the point where it contacts the circle.

• The angle generated when two chords meet on the circle's boundary is called an inscribed angle.
• Angles formed by the same arc on the circumference of the circle are always equal.
• The formula is used to calculate the area of a circle.$A=\mathrm{\pi }{r}^2$
• The formula is used to calculate the perimeter or circumference of a circle.$P=2\mathrm{\pi }r$
