What are supplementary and complementary angles?

If the sum of two angles is 180 degrees then they are said to be supplementary angles, which forms a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.

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°.

What are supplementary angles?

Definition of supplementary angles



: two angles or arcs whose sum is 180 degrees.

How do you determine complementary and supplementary angles?

Video quote: And the supplement of an angle and the the definition is we say two positive angles are complementary. If when we add their angles together we get 90 degrees.

What does complement mean in math?

The complement of a set in math is defined as a set of elements in the universal set that is not part of the original set.

What is the complementary angle of 59?

1 Answer. The complement is 31∘ .

Is 46 and 45 complementary?

Match the angles that are complementary.



Complementary Angles.

What is the complement of 38 degrees?

The complement of 38° is the angle that when added to 38° forms a right angle (90° ).

What is the supplementary angle to 128?

Answer: 52 degrees. Step-by-step explanation: plzzzzzzzzzzzzzzz mark as brainliest.

What is the sum of complementary angle?

90 degrees

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 angle of 134?

Explanation: The opposite, or supplementary, angle would be 46 degrees because a straight angle = 180 degrees, and the supplementary angle = the measure of a straight angle minus the original angle. Therefore, the supplementary angle = 180-134.

What is in obtuse angle?

An obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees. It’s not clear why these angles take that name, as the word ‘obtuse’ can be defined as ‘stupid’.

What is a zero angle?

Zero Angles



An angle with a measure of zero degrees is called a zero angle. If this is hard to visualize, consider two rays that form some angle greater than zero degrees, like the rays in the . Then picture one of the rays rotating toward the other ray until they both lie in the same line.

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 an oblique angle?

: an angle that is not 90 degrees : an acute or obtuse angle. The dancer held his leg at an oblique angle to his body.

What are the 5 types of angle?

The different types of angles based on their measurements are:

• Acute Angle – An angle less than 90 degrees.
• Right Angle – An angle that is exactly 90 degrees.
• Obtuse Angle – An angle more than 90 degrees and less than 180 degrees.
• Straight Angle – An angle that is exactly 180 degrees.

What is an acute angle?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

What are adjacent angles?

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. When you break down the phrase adjacent angles, it becomes easy to visualise exactly what it is; they are two angles that are next to each other.

What is in the scalene triangle?

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

What are corresponding angles?

Definition: Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal). For example, in the below-given figure, angle p and angle w are the corresponding angles.

What is the complement of 45?

90°

The complement of 45° is the angle that when added to 45° forms a right angle (90° ).

What is the complement of 55?

In a triangle the complementary of an angle is = 90 degrees. since one angle is 55 degrees. Therefore answer is 35 degrees.

What is the supplement of 19 degrees?

The supplementary angle adds to 180. So if the given angle is 19, then the complementary angle is 90-19=71. Step-by-step explanation: If one angle is 19, then the other is 180 – 19 or 161 degrees.

What is the complement of 67?

The complement of 67° is the angle that when added to 67° forms a right angle (90° ).

What is the complement of 81?

Answer: the complement of 81° is 9.

What is the supplementary angle of 89 degrees?

The supplement of 89° is the angle that when added to 89° forms a straight angle (180° ).
