# Quick Answer: What Is A Inscribed Angle In Math?

## What is an inscribed angle and how do I find its measurement?

The measure of an inscribed angle is half the measure of the intercepted arc. That is, m∠ A BC=12m∠ A OC. This leads to the corollary that in a circle any two inscribed angles with the same intercepted arcs are congruent.

## What is 2 inscribed angles?

In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle. Equivalently, an inscribed angle is defined by two chords of the circle sharing an endpoint.

## What is an inscribed?

1: to write, engrave, or print as a lasting record His name is inscribed on the monument. 2: to write, engrave, or print something on or in inscribe a book. inscribe. transitive verb. in·​scribe.

## What is the measure of XYZ?

Answer Expert Verified Angle subtended by an arc at the centre is twice of the angle subtended at any point on the circle. And in the given diagram, angle subtended on the circle by arc XZ=60 degree. So arc XZ =2*60=120. Therefore measurement of arc xyz=360-120=240 degree.

## What do you call the longest chord?

The longest chord of a circle should pass through the centre of the circle, only then will it acquire a length greater than any other. And, the chord that passes through the centre of a circle is called the diameter. Hence, the longest chord is the diameter. Hope you liked the answer.

## What are the 7 circle theorems?

• Circle Theorem 2 – Angles in a Semicircle.
• Circle Theorem 3 – Angles in the Same Segment.
• Circle Theorem 4 – Cyclic Quadrilateral.
• Circle Theorem 5 – Radius to a Tangent.
• Circle Theorem 6 – Tangents from a Point to a Circle.

## What are the 9 circle theorems?

Circle theorems: where do they come from?

• The angle at the centre is twice the angle at the circumference.
• The angle in a semicircle is a right angle.
• Angles in the same segment are equal.
• Opposite angles in a cyclic quadrilateral sum to 180°
• The angle between the chord and the tangent is equal to the angle in the alternate segment.

## Is an angle whose vertex is on the circle?

An angle whose vertex lies on a circle and whose sides intercept the circle (the sides contain chords of the circle ) is called an inscribed angle. These secant lines intersect each other at the vertex of the angle. The measure of such an angle is half the sum of the measures of the arcs it intercepts.

## What does an inscribed angle look like?

An inscribed angle is an angle whose vertex is on a circle and whose sides contain chords of a circle. This is different than the central angle, whose vertex is at the center of a circle. Moreover, if two inscribed angles of a circle intercept the same arc, then the angles are congruent.

## What is circum angle?

Circum angle: A circum angle is subtended between any two chords of a circle having common point on its circumference.

## What do you mean by inscribed circle?

An inscribed circle is the largest possible circle that can be drawn on the inside of a plane figure. For a polygon, each side of the polygon must be tangent to the circle. All triangles and regular polygons have circumscribed and inscribed circles.

## What is the difference between circumscribed and inscribed?

An inscribed polygon is a polygon in which all vertices lie on a circle. The polygon is inscribed in the circle and the circle is circumscribed about the polygon. A circumscribed polygon is a polygon in which each side is a tangent to a circle.

## What does inscribed shape mean?

In geometry, an inscribed planar shape or solid is one that is enclosed by and “fits snugly” inside another geometric shape or solid. A polygon inscribed in a circle is said to be a cyclic polygon, and the circle is said to be its circumscribed circle or circumcircle.
