If two chords intersect inside a circle the angles formed are called inscribed angles.?
yes
If a circle is divided into equal parts so that the angles have a degree measure of 120 how many angles would be formed?
3 angles
What is formed when all points are equidistant from a central point?
A circle.
When chords intersect in a circle are the vertical angles formed intercept congruent arcs?

What are the different types of angles in a circle?
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.
If a circle is divided into 5 sections by 5 radii and each of the central angles formed are of equal measure what is the measure of each central angle?
72 degrees 72 degrees
If two chords intersect inside a circle are the angles formed called inscribed angles?
yes
If two chords intersect inside a circle the angles formed are called inscribed angles.?

A central angle measuring 120 degrees intercepts an arc in a circle whose radius is 6. What is the area of the sector of the circle formed by this central angle?
The area of the sector of the circle formed by the central angle is: 37.7 square units.
If a circle is divided into equal parts so that the angles have a degree measure of 120 how many angles would be formed?
3 angles
What is an angle formed by two radii of a circle called?
central angle central angle
What is formed when all points are equidistant from a central point?
A circle.
If two chords intersect inside inside a circle the angles formed are called inscribed angles. true or false?
False
When two diameters of a circle divide the circle into 4 congruent parts what kind of angle is formed by diameter?
A right-angled (90 degrees) cross (+) is formed by the two diameter lines crossing in the centre of the circle.
What theorems are there for concentric circles?
*If two pair of tangent of inner circle making angles on the circumference of outer circle then the angles so formed are equal . *Any two tangent of inner circle within the outer circle's circumference are equal in length .
