two angles that add up to 90 degrees
.
What is complementary angle answer?
Two angles are called complementary
if their measures add to 90 degrees
, and called supplementary if their measures add to 180 degrees. … For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.
What is complementary angle with example?
Complementary angles are pair angles with the sum of 90 degrees. … Common examples of complementary angles are:
Two angles measuring 45 degrees each
. Angles measuring 30 and 60 degrees. Angles measuring 1 degree and 89 degrees.
Do complementary angles add up to 180?
Two angles are said to be complementary if they add up to 90 degrees.
Two angles are said to be supplementary if they add up to
180 degrees. Here is a short trick for you to understand the difference between supplementary angles and complementary angles.
What is the complementary angle of 90?
The complement of a 90° angle is
a 0° angle
.
Which angle is complementary to 3?
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 formula of complementary angles?
| Supplementary Angles Complementary Angles | A pair of angle are said to be supplementary if their sum is 180 degrees. A pair of angle are said to be complementary if their sum is 90 degrees. | Supplement of an angle x° is (180 – x)° The complement of an angle x° is (90 – x)° |

How do you solve complementary angle problems?
- Find the complement of: (a) 68° Solution: 90° – 68° = 22° …
- Find the complement of the angle (10 + y)°. Solution: Complement of the angle (10 + y)° = 90° – (10 + y)° = 90° – 10° – y° = (80 – y)°
- Find the measure of an angle which is 46° less than its complement.
What is the complementary angle of 60 degree?
The complementary angle of 60° is
30°
.
What are two angles whose measures have a sum of 90?
Supplementary angles are two angles whose sum is 180 degrees while
complementary angles
are two angles whose sum is 90 degrees.
What do we call the two lines that never meet?
Parallel lines
are lines in a plane that are always the same distance apart. Parallel lines never intersect.
What is an example of a vertical angle?
Vertical angles are supplementary angles when the lines intersect perpendicularly. For example,
∠W and ∠ Y are
vertical angles which are also supplementary angles. Similarly, ∠X and ∠Z are vertical angles which are supplementary.
What is the complementary angle of a right angle?
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.
What is the complement of a 25 degree angle?
If the complement of an angle is 25 degrees, then the measurement of the angle will be
65 degrees
. To find the complement of an angle, we subtract the…
What is the complementary angle of 55?
The complement of 55 is
90 – 55
.
