Answer:
1.Radius: The distance from the center of the circle to its outer rim. Chord: A line segment whose endpoints are on a circle. Diameter: A chord that passes through the center of the circle. ... Congruent Circles: Two or more circles with the same radius, but different centers.
2.Major Arcs. What is so amazing about arcs of a circle is that an arc is named according to its angle. A minor arc is less than 180° and is equal to the central angle. The central angle is formed with its vertex at the center of the circle, whereas a major arc is greater than 180°.
3.Theorem 70: The measure of an inscribed angle in a circle equals half the measure of its intercepted arc. The following two theorems directly follow from Theorem 70. Theorem 71: If two inscribed angles of a circle intercept the same arc or arcs of equal measure, then the inscribed angles have equal measure.
