Measure of an angle formed by intersecting chords is half the sum of measures of the intercepted arcs?
true
What is the measure of an angle formed by a tangent and a secant drawn to a circle from an external point if it intercepts arcs whose measures are 70 and 30?
20 degrees
Arcs of a circle that have exactly one point in common are called what?
Adjacent Arcs
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
The measure of a secant-secant angle is 30 Which of the choices below could be the measures of the intercepted arcs?
40, 100 and 83, 143.
The measure of an angle formed by intersecting chords is of the sum of the measures of the intercepted arcs?
It is the measure of half the intercepted arc.
Measure of an angle formed by intersecting chords is half the sum of measures of the intercepted arcs?
true
Are measures of minor arcs equal measures of inscribed angles?
No. The first is a measure of length, the second is a measure of angular displacement. If you have two circles with arcs of the same angular measure, the lengths of the arcs will not be the same.

20 degrees
The measure of a tangent-tangent angle is half the difference of the measures of the intercepted arcs?
True

It measures half the sum of the arcs it intercepts.
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
The measure of a secant-secant angle is 30 Which of the choices below could be the measures of the intercepted arcs?
40, 100 and 83, 143.
The measure of a secant-secant angle is 35 Which of the choices below could be the measures of the intercepted arcs?
