Not true. If the associated central angles are equal, the two chords would be equal.
They can be but not always because supplementary angles add up to 180 degrees.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
Not always. If two angles are congruent then they simply have equal measure. They must only be right angles if they are supplementary, that is, they must both add up to 180 degrees.
45° and 45°. Maybe the other way around.
A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
Angles that are congruent and supplementary must be right angles.
They are congruent angles
No, a pair of angles that are supplementary will always have a sum of 180 degrees, while a pair of angles that are congruent will have the same measure. Therefore, it is not possible for a pair of angles to be both supplementary and congruent.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
They are supplementary
congruent
They can be but not always because supplementary angles add up to 180 degrees.
Supplementary Congruency Theorem
Give us a break! -- A 3° angle is congruent to another 3° angle, but their sum is only 6° , not 180°. -- Congruent angles are always equal, but supplementary angles don't have to be equal.
supplementary angles are equal to 180 degrees. so two congruent(same) angles would be 90 degrees!
Congruent *apex
They can be but not always because supplementary angles add up to 180 degrees.
