Quick Answer: What Is A Supplementary Angle In Geometry?

Two angles are called supplementary when their measures add up to 180 degrees.

What is a supplementary angle example?

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.

What is the definition of supplementary angles in geometry?

: two angles or arcs whose sum is 180 degrees.

What is the supplement of an angle?

The supplement of an angle is what, when added to it, equals 180 degrees. For example, in your problem, 180°-85°=95°. This means that the supplement of 85° is 95°, since they add up to equal 180 degrees a straight angle.

What does complementary mean in geometry?

: two angles that add up to 90 degrees.

What is the supplement of 93 degrees?

93° and 87° are supplementary angles.

How do you find a supplementary angle?

Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don’t have to be together.

What are supplementary angles and complementary angles?

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

How do you find supplementary angles?

How to Find 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.

What do u mean by supplementary?

1: added or serving as a supplement: additional supplementary reading. 2: being or relating to a supplement or a supplementary angle.

Which of the following angles are supplementary?

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. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180°.

What does a complementary angle look like?

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

How are 1 and 2 related They are supplementary?

∠1 and ∠2 are supplementary. If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.

How do you find complementary and supplementary angles?

If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. 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.
