let the two circles with centre O and P are congruent circles, therefore their radius will be equal.
given: AB and CD are the chords of the circles with centres O and P respectively.
∠AOB=∠CPD
TPT: AB=CD
proof:
in the ΔAOB and ΔCPD
AO=CP=r and OB=PD=r
∠AOB=∠CPD
therefore by SAS congruency, ΔAOB and ΔCPD are congruent triangle.
therefore AB=CD
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
they have 4 congruent angles
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Two angles that are congruent have the same angle measurement.
A triangle with three congruent angles
Yes, congruent central angles in a circle have congruent chords. This is because the length of a chord is determined by the angle subtended at the center of the circle; when two central angles are equal, the arcs they subtend are also equal, leading to chords of the same length. Thus, congruent central angles correspond to congruent chords.
Chuck Norris can prove it
If two chords in a circle are congruent, then they are equidistant from the center of the circle. This means that the perpendicular distance from the center to each chord is the same. Additionally, congruent chords subtend equal angles at the center of the circle.
None normally but it does have 2 congruent parallel circles and there are 360 degrees around a circle.

Yes, two arcs of a circle are congruent if and only if their associated radii are congruent. This is because congruent arcs subtend equal angles at the center of the circle, which means the radii connecting the center to the endpoints of the arcs must also be equal in length. Thus, the congruence of the arcs directly correlates to the congruence of their respective radii.
Yes, supplements of congruent angles are congruent. If two angles are congruent, they have the same measure. When you take the supplements of these angles, the resulting angles will also have the same measure, making them congruent as well.
The prime purpose of a compass is to construct circles.
Angles are congruent if they are equal. Corresponding angles in figures that are similar are congruent.
if two angles are supplements of congruent angles, then the two angles are congruent.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
