# How many degrees is a complementary angle?

Last Updated: 13th March, 2020

12
Two Angles are Complementary when they add up to 90degrees (a Right Angle). They don't have to be next to eachother, just so long as the total is 90 degrees. Examples:60° and 30° are complementary angles.

Consequently, what is the measure of complementary angle?

Straight lines measure 180°. That means thatthese two angles are supplementary. Complementaryangles form a right angle (L shape) and have a sum of 90degrees. Supplementary angles form a straight line and havea sum of 180 degrees.

One may also ask, can 3 angles be complementary? Three or more angles are also not calledcomplementary, even if their measures happen to add up to 90degrees.

what is complementary angle and supplementary angle?

Supplementary angles are two angles whosesum is 180 degrees while complementary angles are twoangles whose sum is 90 degrees. Supplementary andcomplementary angles do not have to be adjacent (sharing avertex and side, or next to), but they can be.

What is the complementary angle of 38 degrees?

Complementary angles are two angles thatequal 90 degrees when their measures are added together. Forexample, an angle of 15 degrees would have acomplementary angle of 75 degrees.

## What is a reflex angle?

An acute angle is an angle that measuresbetween 0 and 90 degrees, and an obtuse angle is anangle that measures between 90 and 180 degrees.

## What is complementary angle with diagram?

In a right angled triangle, the two non-rightangles are complementary, because in a triangle thethree angles add to 180°, and 90° has already beentaken by the right angle. When two angles add to90°, we say they "Complement" each other. Complementarycomes from Latin completum meaning "completed" Pundit

## What is adjacent angle?

## What is the complement of 60 degrees?

If your angle is 30 degrees, then itscomplement is 60 degrees because 60 + 30 = 90.If your angle is 30 degrees, then its supplement is150 degrees because 30 + 150 = 180. Pundit

## Which angle is supplementary to Doc?

Two angles are supplementary when they addup to 180 degrees. 1. Consider angle ∠COB:m∠DOC+m∠COB=m∠DOB=180°. Pundit

## How do you solve supplementary angles?

Supplementary Angles
1. Let the measure of one of the supplementary angles be a .
2. Measure of the other angle is 2 times a .
3. So, measure of the other angle is 2a .
4. If the sum of the measures of two angles is 180° , then theangles are supplementary.
5. So, a+2a=180°
6. 3a=180°
7. To isolate a , divide both sides of the equation by 3 .
8. 3a3=180°3 a=60° Pundit

## What types of angles are supplementary?

Lesson Summary
You learned that complementary angles are twoangles that add up to 90 degrees, supplementaryangles are two angles that add up to 180 degrees,vertical angles are opposite angles at anintersection of two straight lines, and adjacent angles aretwo angles that are next to each other. Teacher

## Are vertical angles supplementary?

Vertical angles are always congruent, or of equalmeasure. Both pairs of vertical angles (four anglesaltogether) always sum to a full angle (360°). Adjacentangles. In the figure above, an angle from each pairof vertical angles are adjacent angles and aresupplementary (add to 180°). Teacher

## Can 2 adjacent angles be supplementary?

Adjacent Angles are two angles that sharea common vertex, a common side, and no common interior points. Iftwo angles form a linear pair, the angles aresupplementary. A linear pair forms a straight angle whichcontains 180º, so you have 2 angles whose measures addto 180, which means they are supplementary. Teacher

## Can two angles in a triangle be supplementary?

Two angles are said to be supplementary iftheir sum is equal to 180 degrees. It is not possible to for twoangles of a triangle to besupplementary. Teacher

## What is vertically opposite angle?

Vertically Opposite Angles. VerticallyOpposite Angles are the angles opposite each other whentwo lines cross. "Vertical" in this case means they sharethe same Vertex (corner point), not the usual meaning ofup-down. Reviewer

## Can negative angles be complementary?

Complementary angles add to 90 degrees. So if twoangles are complementary, then they are acute (ieless than 90 degrees). So it's not possible for an obtuseangle to have a complementary angle. There is nothingin the definition that would exclude one of the angles fromhaving a negative measure. Reviewer

## Can two angles be complementary?

Complementary angles are 2 angles whosemeasures add to 90 degrees. Supplementary angles are 2angles whose measures add to 180 degrees. Thecomplementary and supplementary angles do not have tobe adjacent. Reviewer

## Can 2 acute angles be complementary?

Complementary angles are those angleswhose sum is equal to 90o. Thus, complementaryangles are always acute angles. Hence, two acuteangles can be complementary. Question2:Can two obtuse angles complement eachother? Reviewer
