Measure of an angle formed by intersecting chords is half the sum of measures of the intercepted arcs?
true
What is the measure of angle abc in a circle 134 degrees?
In a circle, the measure of an angle formed by two chords that intersect at a point inside the circle is equal to the average of the measures of the arcs intercepted by the angle. If angle ABC measures 134 degrees, it means that the angle is formed by the intersection of two chords, and the measure of the arcs it intercepts will average to this angle. Thus, angle ABC is 134 degrees.
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 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.
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
The measure of a tangent-tangent angle is half the difference of the measures of the intercepted arcs?
True
