How do you solve supplementary and complementary 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.

How do you solve complementary angles?

How to Find Complementary Angles? If the sum of two angles is 90 degrees, then we say that they are complementary. Thus, the complement of an angle is obtained by subtracting it from 90. For example, the complement of 40° is 90° – 40° = 50°.

How do you find supplementary angles?

Video quote: So according to the definition of supplementary angle two angles are said to be supplement to each other when their sum is equal to 180 degrees so here our angle given angle is 105 degree.

What are supplementary angles?

Definition of supplementary angles



: two angles or arcs whose sum is 180 degrees.

What is supplementary math?

In Maths, the meaning of supplementary is related to angles that make a straight angle together. It means, two angles are said to be supplementary angles when they add up to 180 degrees. Two angles are supplementary, if. One of its angles is an acute angle and another angle is an obtuse angle.

What is a complementary angle example?

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.

What is supplementary angle and 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.

What is the supplement of 102 degrees?

Step-by-step explanation:



If the supplement is 102° then the angle is 180° – 102° which is 78°.

What is the supplementary angle of 103?

The supplementary angle of 103° is 77 The complementary angle of 37° is 33.

What angle is complement to 56?

90°

The complement of 56° is the angle that when added to 56° forms a right angle (90° ).

What is a 180 angle?

Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles. • Angles that are 360 degrees (θ = 360°) are full turn.

How do you draw a protractor?

Video quote: I first need to create a ray to do that I can simply use the bottom edge of my protractor as a straight edge to draw a line. We know rays will go on forever in one direction.

What is reflex angle?

A reflex angle is any angle that is more than 180 degrees (half circle) and less than 360 degrees (full circle). A reflex angle will always have either an obtuse or an acute angle on the other side of it.

What is in the scalene triangle?

A scalene triangle is a triangle that has three unequal sides, such as those illustrated above.

What is a obtuse equilateral?

The angles in an equilateral triangle are all 60 degrees. 1803=60. since all three angles are equal divide the total degrees in an triangle by 180 by 3. An obtuse angle is greater than 90 degrees. 60< 90 so an equilateral triangle can not have an obtuse angle.

What is a right equilateral?

Video quote: A triangle with one right angle is called a right triangle.

What is a triangle with 3 unequal sides called?

3. Now, let’s move on to scalene triangles. A scalene triangle has three unequal sides. It also has three unequal angles. On the other hand, an equilateral triangle is one in which the length of all sides are equal.

Can a triangle be scalene and right?

In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).

What is a trapezoid shape?

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
