Half of 90...
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
Let the angle be ( x ) degrees. Its complement is ( 90 - x ) degrees. Given the ratio of the angle to its complement is ( \frac{1}{2} ), we can set up the equation ( \frac{x}{90 - x} = \frac{1}{2} ). Solving this, we find ( x = 30 ) degrees, so the complement is ( 90 - 30 = 60 ) degrees.
The complement of a 40-degree angle is found by subtracting the angle from 90 degrees. Therefore, the complement is 90 - 40 = 50 degrees. This means that a 50-degree angle, when added to a 40-degree angle, will equal 90 degrees.
Interior angle+exterior angle = 180 degrees
The complement is 60 degrees.
The word complement means "something that completes." (That's why it's spelled complement,as opposed to compliment, a favorable comment.) In geometry, the complement is the angle needed to complete a right angle. Thus,90° - known quantity = complement
67.5 degrees

A congruent angle can also mean equal angle. So there is no set measurement of a congruent angle. Just the same as the angle it is equal to.
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
Let the angle be ( x ) degrees. Its complement is ( 90 - x ) degrees. Given the ratio of the angle to its complement is ( \frac{1}{2} ), we can set up the equation ( \frac{x}{90 - x} = \frac{1}{2} ). Solving this, we find ( x = 30 ) degrees, so the complement is ( 90 - 30 = 60 ) degrees.
60 degrees.
The angle= 36, the supplement= 144, the compliment=54
Complementary angles add up to equal 90 degrees. If one angle is already known to be 80 degrees, the remaining complement to the angle would be 10 degrees.
Interior angle+exterior angle = 180 degrees
The complement is 60 degrees.
Since the sum of the two complement angles is 90⁰ , then the complement of a 60⁰ angle is a 30⁰ angle.
