Given: Two congruent circles C1 & C2 AB is the chord of C1 & PQ is the chord of C2 & AOB = PXQ To prove: Chords are equal, i.e., AB = PQ Proof: In AOB & PXQ AO = PX AOB = PXQ BO = QX AOB PXQ AB = PQ Circle Exercise 10.2. Congruent. Thus, all of the corresponding sides of the two pieces of paper do not have the same length, so they are not congruent. This question hasn't been answered yet Ask an expert. Two arcs are congruent if and only if they have the same measure within one circle or within two congruent circles. Markings on shapes are the best way to compare sides and angles to see if they are equal or congruent Circles too can be congruent. two circles are congruent if they have the same _____ chord. Solution. secant. Two circles are congruent, if and only if they have equal radii. The terms radius and diameter describe segments as well as measures. Theorems of Arcs, Chords & Angles… Theorem 79: If two central angles of a circle … B) all of their chords will be congruent. 21. if two circles are congruent then A) they will have the same area.
