What is the use of complementary angles?
What is the use of complementary angles?
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
How are angles used in real life?
Angles are used in daily life. Engineers and architects use angles for designs, roads, buildings and sporting facilities. Carpenters use angles to make chairs, tables and sofas. Artists use their knowledge of angles to sketch portraits and paintings.
What are some examples of supplementary angles?
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°….Some of the examples of supplementary angles are:
- 120° + 60° = 180°
- 90° + 90° = 180°
- 140° + 40° = 180°
- 96° + 84° = 180°
What are complementary angles?
: two angles that add up to 90 degrees.
What is a real life example of an acute angle?
Some real-life examples of acute angles are: If we slice a pizza into 5 or more slices, each slice of pizza will make an acute angle. Each slice of the pizza makes an acute angle. Another example is the wall clock. The arms of a wall clock make acute angles at several hours of a day.
What is a real life example of an obtuse angle?
Examples of Obtuse Angles in Everyday Life Take a look at the hands on this clock. The angle formed by the clock hands is obtuse because it measures between 90º and 180º. On analog clocks, you can find even more examples of times when obtuse angles are formed by the clock hands, for example, 3:35.
What is the supplement of 93 degrees?
93° and 87° are supplementary angles.
How do you find complementary angles?
In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they “Complement” each other. because the right angle is thought of as being a complete angle.
What is the complement of 47?
43°
The angle that is complementary to 47° is 43°.
How are supplementary angles used in real life?
Supplementary angles are made when two angles equal a sum of 180 degrees. Some real life examples of supplementary angles are stars, cups and logos.
