Never.

The sum of all three angles of a triangle, each of which is greater than 0 degrees, is 180 degrees. So two of them cannot add to 180 deg.

Are the angles of a triangle considered to be supplementary?

This question could be argued over and over. However, my interpretation of "supplementary" is TWO angles add up to be 180. However, there are THREE angles in a triangle, so the angles of a triangle, although they add up to 180, are not supplementary.


Are acute angles of a right triangle are supplementary?

No, they are complimentary (add to 90°) Supplementary means the two angles add to 180°


Is a triangle supplementary or complementary?

In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they "Complement" each other.


What is the term for the sum of angles of the triangle?

supplementary angles.


Are the two acute angles in a right triangle supplementary?

No, they are complementary angles. Supplementary angles sum to 180o Complementary angles sum to 90o. The three angles of a triangle sum to 180o. If one is 90o (the right angle), then the other two sum to 180o - 90o = 90o and so are complementary.


Is it possible to draw a triangle with a pair of supplementary angles?

No, because the sum of the 3 angles of a triangle always equals 180 degrees. If two angles are supplementary by definition the two together already sum to 180 degrees, leaving no "space" for the third angle.


Can two acute angles cannot be supplementary?

Two acute angles cannot be supplementary but they can be complementary


How many degrees are in supplementary angles?

Supplementary angles are two angles which add up to 180°.


What are supplementary estimates?

Supplementary angles - two angles that add up to 180 degrees. No matter how large or small angles 1 and 2 on the left become, the two angles remain supplementary which means that they add up to 180°. By the way, supplementary angles do not need to be adjacent angles(angles next to one another) if it doesnt add up to 180 then they are not supplementary angles, but if they do then they are supplementary angles.


What does supplementary mean in angles?

Two supplementary angles add up to 180 degrees


What is the sum of the measurements of two supplementary angles?

Supplementary angles total 180 degrees.


Can two angles be supplementary?

Yes. A supplementary angle is two angles with a common ray that equal 180 degrees.
