Are central angles equal to the measure of their intercepted arcs?
Yes as for example in the case of a sector of a circle.
Measure of an angle formed by intersecting chords is half the sum of measures of the intercepted arcs?
true
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 45 Which of the choices below could be the measures of the intercepted arcs?
74, 164 36, 126 18, 108

What measure of a intercepted arc?
Examples to show how to use the property that the measure of a central angle is equal to the measure of its intercepted arc to find the missing measures of arcs and angles in given figures.
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.
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.
Measures of minor arcs equal measures of inscribed angles?
lol. your on odyssey ware
The measure of a tangent-tangent angle is half the difference of the measures of the intercepted arcs?
True
Measure of an angle formed by intersecting chords is half the sum of measures of the intercepted arcs?
true
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
What does parallel lines intercepted arc conjecture mean?
Parallel lines intercept congruent arcs on a circle. More explanation: Parallel lines never interSECT but they can interCEPT Congruent arcs means that the two arcs would have the same measure of the 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?
56, 126,40, 110,and 77, 147.
What is the relation between the arc length and angle for a sector of a circle?
A sector is the area enclosed by two radii of a circle and their intercepted arc, and the angle that is formed by these radii, is called a central angle. A central angle is measured by its intercepted arc. It has the same number of degrees as the arc it intercepts. For example, a central angle which is a right angle intercepts a 90 degrees arc; a 30 degrees central angle intercepts a 30 degrees arc, and a central angle which is a straight angle intercepts a semicircle of 180 degrees. Whereas, an inscribed angle is an angle whose vertex is on the circle and whose sides are chords. An inscribed angle is also measured by its intercepted arc. But, it has one half of the number of degrees of the arc it intercepts. For example, an inscribed angle which is a right angle intercepts a 180 degrees arc. So, we can say that an angle inscribed in a semicircle is a right angle; a 30 degrees inscribed angle intercepts a 60 degrees arc. In the same or congruent circles, congruent inscribed angles have congruent intercepted arcs.
