Chords IV 4/19

What determines both chords and arcs in a circle?

• The circle's circumference

• Points on the circle

• The radius of the circle

• The circle's diameter

If two minor arcs are congruent, what else is true about their corresponding chords?

• They have different lengths

• They are congruent

• They are perpendicular to each other

• They intersect at the circle's center

How do you find the length of a chord bisected by a radius?

• Divide the radius by 2

• Multiply the radius by 2

• Use the Pythagorean theorem

• Subtract the radius from the diameter

What theorem is used to solve for the short side of a right triangle in a circle?

• The Pythagorean theorem

• The central angle theorem

• Euler's theorem

• The theorem of congruent chords

Chords that are equidistant from the center of a circle are:

• Always perpendicular to the radius

• Congruent

• Different in length

• Not related to each other
