No, supplementary angles are not always congruent, and we can demonstrate this by showing an example of two supplementary angles that are not…
Q. Which type of angle pairs are only sometimes supplementary?
Sometimes. A linear pair is by definition supplementary, but two supplementary angles are only a linear pair if they are also adjacent.

Q. What are 2 examples of supplementary angles?
Supplementary angles are those angles that measure up to 180 degrees. For example, angle 130° and angle 50° are supplementary because on adding 130° and 50° we get 180°….Some of the examples of supplementary angles are:
- 120° + 60° = 180°
- 90° + 90° = 180°
- 140° + 40° = 180°
- 96° + 84° = 180°
Q. Are linear pairs always sometimes but not always or never supplementary?
If two angles are a linear pair then they are adjacent. You just studied 8 terms!
Q. Can 2 obtuse angles be supplementary?
Hence, two obtuse angles i.e., angle which is greater than 90 degrees, can never be supplementary as their sum is not coming equal to 180∘ and to be supplementary the angles sum should be equal to 180∘.
Q. What is the formula of supplementary angles?
We can calculate supplementary angles by subtracting the given one angle from 180 degrees. To find the other angle, use the following formula: ∠x = 180° – ∠y or ∠y = 180° – ∠x where ∠x or ∠y is the given angle.
Q. Can two angles be supplementary?
Thus, the two acute angles cannot be supplementary angles. Thus, the two obtuses angles cannot be supplementary angles. Thus, two right angles are supplementary angles.
Q. Can 3 angles be supplementary?
No, three angles can never be supplementary even though their sum is 180 degrees.
Q. How many angles can be supplementary?
Two angles
Q. How do you know if angles are congruent or supplementary?
A ∠ ≅ ∠ .
- Vertical Angles Theorem:
- If two angles are supplements of the same angle (or congruent angles), then the two angles are congruent.
- If two angles are complements of the same angle (or congruent angles), then the two angles are congruent.
- If two angles are congruent and supplementary, then each is a right angle.
Q. Which of the following is not a pair of supplementary angles?
Answer: 2) 135° and 45° are supplementary angles. 3) 50° and 140° are not supplementary angles because their sum is not equal to 180 degree.
Q. Which angle is supplementary to Doc?
1. Consider angle ∠COB: m∠DOC+m∠COB=m∠DOB=180°. This means that angles ∠DOC and ∠COB are supplementary.
Q. Is it possible to find the complement angle of 103?
Is it possible to find the complement angle of 103°? If so, what is it? Not possible.
Q. Which of the following is a pair of complementary angles?
Two angles whose sum is 90° (that is, one right angle) are called complementary angles and one is called the complement of the other. Here, ∠AOB and ∠BOC are called complementary angles. ∠AOB is complement of ∠BOC and ∠BOC is complement of ∠AOB.
Q. What do we call the two angles with equal measure?
congruent angles
Q. Can a pair of angles be complementary and supplementary?
Yes, because the sum of two angles is 180, and if they are both 90 degrees, they add up to 180, making them supplementary, and of the same measure, making them congruent.
Q. How many right angles are there in a complete angle?
Four right angles
Q. Can a trapezoid have 2 right angles?
A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base.
Q. Are all angles of rhombus 90?
In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.
Q. Does a rhombus have a 90 angle?
The intersection of the diagonals of a rhombus form 90 degree (right) angles. This means that they are perpendicular. The diagonals of a rhombus bisect each other. This means that they cut each other in half.
