Supplementary Angles Calculator:Our user-friendly Supplement Angle Calculator allows to find whether the given two angles are supplement or not and also obtains the supplementary angle for the provided input angle. Check the following sections to know the complete details about supplemenatry angles and how to calculate the supplementary angle. Also, find the solved example questions.

What are Supplementary Angles?

The word supplementary describes a special relationship between two angles. The supplementray angles defination says that the sum of two angles is equal to 180° or π. In other words, if the the adjacent angles form a straight line, then are supplemenatry angles.

Two angles are called supplemenatry angles when

  • One of its angle is an acute angle and other is an obtuse nagle.
  • Both angles are right angles

Properties of Supplementary Angles

  • The two angles are called supplemenatary angles only when their sum is 180°.
  • The two angles together make a straight line, but angles need to be together.
  • The letter "S" in supplementary angles stands for "Straight line".

Supplementary Angle Formula

The supplementary angles formula is here:

Supplementary Angle = 180° - angle = π - angle

Examples:

Some of the examples of supplementary angles are:

  • 120° + 60°= 180°
  • 150°+ 30° = 180°
  • 115° + 65° = 180°

How to Calculate Supplementray Angle?

Here are the steps to find the supplementary angle.

  • You have to know atleast one angle to know its supplement.
  • Subtract the angle from 180°.
  • The difference angle is called the supplementary angle.

Steps to Check 2 Angles are Supplementary or Not

  • Get the values of two angles.
  • Add those two angles.
  • If the sum is equal to π, then they are supplement.
  • Otherwise, they are not supplementary angles.

Examples on Supplementary Angles

Example 1:

Check if 89° and 95° are supplementary angles.

Solution:

Given two angles are 89° and 95°

Find the sum of angles

89° + 95° = 184°

As the sum is not equal to 180°, the angles are not supplementary.

Example 2:

Find the supplementary angle for 86°

Solution:

Given angle is 86°

To get the supplementray angle, find the difference between 180° and 86°

180° - 86°= 94°

Therefore, supplementary angle for 86° is 94°.

FAQs on Supplementray Angles Calculator

1. Do supplementary angles add up to 360°?

No, supplementray angles addition is not equal to 360°.

2. What is the supplementary angle of 95°?

The supplementary angle of 95° is 180° - 95° = 85°.

3. How do you find supplementary angles?

To find the supplementary angles, we have to subtract one angle from 180 degrees. THe difference is the supplementary for the given nagle.

4. What is supplementary angle with example?

Supplementary angles are two angles whose add up to 180 degrees. The 2 angles of a liner pair are supplementary. The example for supplementary angles is 50° and 130°.
