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 is half the sum of the measures of the intercepted arcs.?
The measure of an angle formed by two intersecting chords in a circle is equal to half the sum of the measures of the intercepted arcs. This means that if two arcs, ( A ) and ( B ), are intercepted by the angle, the angle's measure can be calculated using the formula: ( \text{Angle} = \frac{1}{2} (mA + mB) ), where ( mA ) and ( mB ) are the measures of the intercepted arcs. This relationship helps in solving various problems involving angles and arcs in circle geometry.
True or false The measure of a tangent-tangent angle is half the difference of the measures of the intercepted arcs.?
True. The measure of a tangent-tangent angle is indeed half the difference of the measures of the intercepted arcs. This theorem applies to angles formed outside a circle by two tangents that intersect at a point, providing a relationship between the angle and the arcs it intercepts.
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

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.

True
Arcs of a circle that have exactly one point in common are called what?
Adjacent Arcs
