Right 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.
Supplementary angles are congruent when each angle measures 90 degrees. This occurs because supplementary angles are defined as two angles whose sum equals 180 degrees. Therefore, if both angles are equal and their sum is 180 degrees, they must each be 90 degrees.
The Congruent Supplement Theorem states that if two angles are supplementary to the same angle (or to congruent angles), then those two angles are congruent to each other. In other words, if angle A and angle B are both supplementary to angle C, then angle A is congruent to angle B. This theorem is useful in proving relationships between angles in geometric proofs.
Definition of a supplementary angle: an angle that is supplementary to another angle is an angle in which the sum of both angles forms a straight line or 180 degrees.Definition of a right angle: an angle whose measure is 90 degrees.Using these terms, let's put them into an equation.Right angle + Supplementary angle = 180.90 + Supplementary angle = 180.Subtract 90 from both sides.Supplementary angle = 180 - 90Supplementary angle = 90 degrees.Alternatively, you can think that two right angles are equivalent to a straight line and that all right angles are congruent and therefore; their supplementary angles are also congruent.
- A rhombus had four sides and four angles - All four sides of a rhombus are congruent - Both pairs of opposite angles of a rhombus are congruent - One angle of a rhombus is supplementary to both of its consecutive angles - The diagonals of a rhombus bisect each other and are perpendicular - Both pairs of opposite sides of a rhombus are parallel
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.
Right angles.
Only if they both equal 90 degrees.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
Supplementary angles are congruent when each angle measures 90 degrees. This occurs because supplementary angles are defined as two angles whose sum equals 180 degrees. Therefore, if both angles are equal and their sum is 180 degrees, they must each be 90 degrees.
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.

In the context of two parallel lines and an intercept, they are called interior angles.
- A rhombus had four sides and four angles - All four sides of a rhombus are congruent - Both pairs of opposite angles of a rhombus are congruent - One angle of a rhombus is supplementary to both of its consecutive angles - The diagonals of a rhombus bisect each other and are perpendicular - Both pairs of opposite sides of a rhombus are parallel
If they both add up to 180 degrees then they are supplementary angles.
whenever you have a supplementary angle, you know that both of the angles in the supplementary angles will add up to 180 degrees. if that's what you meant
