No they do not unless it is a circle with radius (180/pi) and the angles are measured in degrees, or a circle with radius (1/pi) and the angles are measured in radians.
Yes as for example in the case of a sector of a circle.
true
½ the sum of the intercepted arcs.

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.
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.
It is the measure of half the intercepted arc.
lol. your on odyssey ware
True
To solve circle geometry problems, remember to identify the properties of circles, such as radius, diameter, circumference, and area. Use the formulas for these properties to calculate missing values. Additionally, understand the relationships between angles and arcs in circles, such as central angles, inscribed angles, and intercepted arcs. Practice applying these concepts to various circle problems to improve your skills.
true
½ the sum of the intercepted arcs.
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.

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.
