Central angle - ANSWERS-is equal to its intercepted arc.
,Inscribed angle - ANSWERS-is equal to ½ its intercepted arc.
Angle formed by 2 chords intersecting in a circle - ANSWERS-is
equal to the sum of the arcs divided by 2.
Angle formed by 2 secants - ANSWERS-is equal to the major arc
minus the minor arc divided by 2.

minus the minor arc divided by 2.
Lengths of 2 intersecting chords - ANSWERS-part of the first chord
times the other part of the first chord equals a part of the second
chord times the other part of the second chord.
Lengths of an intersecting diameter and chord that meet at right
angles (perpendicular) - ANSWERS-if a diameter meets a chord at a
right angle (perpendicular), the diameter divides the chord into 2
equal parts.

side, but not common interior points.
Complementary angles - ANSWERS-2 angles when added together
that equal 90 degrees.
They do not have to be adjacent angles.
Supplementary angles - ANSWERS-2 angles when added together
that equal 180 degrees.They do not have to be adjacent angles.
