## Are inscribed angles congruent?

In a circle, any two inscribed angles with the same intercepted arcs are congruent.

## Is the inscribed angle the same as the arc?

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle. Therefore, the angle does not change as its vertex is moved to different positions on the circle.

## Is a central angle congruent to its arc?

A central angle is an angle formed by two radii with the vertex at the center of the circle. In a circle, or congruent circles, congruent central angles have congruent arcs.

## How do you know if a central angle is congruent?

In the same circle, or congruent circles, congruent central angles have congruent arcs. In the same circle, or congruent circles, congruent central angles have congruent chords. In the same circle, or congruent circles, congruent chords have congruent central angles.

## What does it mean if two arcs are congruent?

If two arcs are both equal in measure and they’re segments of congruent circles, then they’re congruent arcs. Notice that two arcs of equal measure that are part of the same circle are congruent arcs, since any circle is congruent to itself. Congruent arcs have equal length (you can prove this yourself).

## How do you know if two arcs are congruent?

The only time two arcs are congruent is when they have the same length measure, not the same degree measure. The example below shows two arcs with the same degree measure, but do not have the same length. Two arcs are congruent if and only if they have the same measure within one circle or within two congruent circles.

## Do congruent chords intersect?

The precise statement of the conjecture is: If two chords of a circle are congruent, then they determine central angles which are equal in measure. If two chords of a circle are congruent, then their intercepted arcs are congruent. Two congruent chords in a circle are equal in distance from the center.

## What shape can fit all other shapes inside of it?

A pyramid is a shape that can fit all shapes inside of it (triangle, square, rectangle, etc.). In geometry, a pyramid is also called a polyhedron.
