What is the interior region of a circle?

What is the interior region of a circle?

The interior part of circle, the region between chord and arc is called segment.

How many regions are in a circle?

4 regions

How do you find the interior of a circle?

An interior angle of a circle is formed at the intersection of two lines that intersect inside a circle. In the diagram above, if b and a are the intercepted arcs, then the measure of the interior angle x is equal to half the sum of intercepted arcs.

Is in the interior of the circle?

Segment of a circle: A region in the interior of a circle enclosed by an arc and a chord is called a segment of a circle. In the figure, XY divides the circular region in two parts – Minor Segment and Major Segment. Circumference: The distance around the circle is called the circumference of the circle.

Which is the longest chord of a circle?


Is a tangent a chord?

A tangent can’t be a chord, because a chord touches a circle in two points, crossing through the inside of the circle. Any radius drawn to a tangent is perpendicular to that tangent.

Are all chords Secants?

A straight line that intersects a circle in two points is called a secant line. A chord is the line segment that joins two distinct points of the circle. A chord is in a unique secant line and every secant line defines a unique chord.

What is the angle between a tangent and a chord called?

The alternate segment theorem (also known as the tangent-chord theorem) states that in any circle, the angle between a chord and a tangent through one of the end points of the chord is equal to the angle in the alternate segment. In the above diagram, the angles of the same color are equal to each other.

Are chords and Secants the same?

Chord is a line segment joining two points on the circle, while secant is a line ‘l’ intersecting the circle in two distinct points.

Can a line be a chord?

In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle. The converse is also true: The locus of all points from which a given segment subtends equal angles is a circle. …
