What is the complementary angle of 120 degrees?

What is the complementary angle of 120 degrees?

The complement of −120° is the angle that when added to −120° forms a right angle (90° ).

How do you find a 120 degree angle?

Constructing a 120° Angle: 120° angle can be constructed using the logic that 60° + 120° = 180°. Thus, we can understand that in order to construct 120° we can construct 60° angle and then further extend one of its arms as shown below in the figure.

How do you find the complementary angle?

To find the complement of an angle, subtract that angle’s measurement from 90 degrees. The result will be the complement. The measure of the complementary angle is 50 degrees.

What is the complementary angle of 150 degrees?

Supplementary angles add up to 180∘ so the supplement is 30∘. Complementary angles add to 90∘ so the complement is −60∘.

What is the angle which is equal to its complement?

45 degrees
Answer: The measure of the angle that is equal to its complement is 45 degrees.

How do you construct a 120 degree and bisect it?

Answer

1. Draw an angle of ∠AOB of 120°.
2. Draw an arc from point O. This arc will cut the ray OA at any point C and ray OB at any point D.
3. Draw two arcs of the same radii from the points C and D as centres.
4. Join the point O to the point M by a ray OM. The ray OM will cut the angle ∠AOB into equal parts.
5. m∠AOM = m∠BOM =

Is a 120 degree angle obtuse acute or right?

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

What is the supplementary angle of 125 degree?

55 degrees
Supplement of 125 degree = 180 – 125 = 55 degrees.

How do you know if its complementary or supplementary?

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.

What is the complementary angle of 60?

30°
The complementary angle of 60° is 30°.
