## What is a supplement and complement in geometry?

Supplementary angles are two angles that have a sum of 180°. Complementary angles are two angles that have a sum of 90°. To determine the supplement, subtract the given angle from 180. 180 – 43 = 137° The supplement of 43° is 137°. To determine the complement, subtract the given angle from 90.

## What does supplementary mean *?

Two angles are called supplementary if a sum of their measures equals to 180o (in degrees) or π radians.

## What is the supplement theorem in geometry?

The supplementary angle theorem states that if two angles are supplementary to the same angle, then the two angles are said to be congruent.

## What is supplementary angle in math?

Supplementary angles are two angles whose measures add up to 180°. The two angles of a linear pair, like ∠1 and ∠2 in the figure below, are always supplementary.

## What is supplement of a number?

When the two angles add to 180°, we say they “Supplement” each other. Supplement comes from Latin supplere, to complete or “supply” what is needed.

## What is the supplement of 47 degrees?

The angle that is complementary to 47° is 43°.

## What does congruent mean in geometry?

congruence, in mathematics, a term employed in several senses, each connoting harmonious relation, agreement, or correspondence. Thus two triangles are congruent if two sides and their included angle in the one are equal to two sides and their included angle in the other.

## What is a vertical angle in geometry?

Vertical angles are angles opposite each other where two lines cross.

## What angles are adjacent?

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way.

## What are supplements of the same angle?

If two angles are supplements of the same angle, then they are congruent. If two angles are congruent, then their supplements are congruent. If two angles form a linear pair, then they are supplementary • If two angles are vertical angles, then they are congruent.

## What is the supplement of an acute angle?

The supplement of an acute angle will always be an obtuse angle. An acute angle is an angle which measures greater than 0 degrees and less than 90

## Are triangles supplementary?

Remember, only a pair of angles can be supplementary. Sure, the three angles in a triangle may add up to 180 degrees, but there are three angles in a triangle, so they are not supplementary!

## What is the supplement of 120 degrees?

The supplementary angle of 120° is 60°.

## What is the supplement of 75 degrees?

The supplementary angle of 75° is 105°.
