What is an example of a complementary angle?

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

How do you use complementary angles in a sentence?

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.

What are complementary angles in trigonometry?

In Mathematics, the complementary angles are the set of two angles such that their sum is equal to 90°. For example, 30° and 60° are complementary to each other as their sum is equal to 90°.

Which of the following angles are complementary?

Complementary Agnles: When the sum of two angles is equal to 90o, they are called complementary angles. In this case, both angles are called complementary to each others. For example 30o and 60o, 40o and 50o, 20o and 70o, etc. are complementary angle since their sum is equal to 90o.

What is the application of angle?

Angles are used in daily life. Engineers and architects use angles for designs, roads, buildings and sporting facilities. Athletes use angles to enhance their performance. Carpenters use angles to make chairs, tables and sofas.

How do complementary angles relate to right angles?

Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).

What does complementary angles mean in geometry?

90 degrees
Definition of complementary angles mathematics. : two angles that add up to 90 degrees.

What does it mean when angles are complementary?

What is the application of trigonometry in real life?

Trigonometry is used to set directions such as the north south east west, it tells you what direction to take with the compass to get on a straight direction. It is used in navigation in order to pinpoint a location. It is also used to find the distance of the shore from a point in the sea.

What are some examples of supplementary angles in real life?

Some of the examples of supplementary angles are: 120° + 60° = 180° 90° + 90° = 180° 140° + 40° = 180° 96° + 84° = 180°

What are some examples of reflex angles in real life?

A reflex angle is an angle that measures more than 180 degrees and less than 360 degrees. What are the examples of reflex angle? The examples of reflex angle are 190 degrees, 220 degrees, 270 degrees, 320 degrees , etc. What is a complete angle?

How are angles measured in real life?

Parts of an Angle Two rays, which are called the sides of the angle. Look at the given image, sides OA and OB are sides of the angle AOB. The vertex of the angle, which has a common endpoint that is shared by the two rays. An angle is measured in degrees. Size of an Angle: The best way to measure the size of an angle is to use a protractor.

How are congruent triangles used in real life?

Construction. Congruent triangles are used in the construction to reinforce the structure. This ensures that the structures are strong and rigid.

Truss Bridge. A truss bridge is formed by equilateral triangles on both sides. All these triangles are congruent under the SSS criteria.

Geodesic Dome. This is common playground equipment.
