Half of 90...
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
The complement is 60 degrees.
Interior angle+exterior angle = 180 degrees
45o This is because 90 minus 45 is 45.
The complement of an angle is equal to 90 degrees minus the measure of the angle. Therefore, the complement of a 72 degree angle would be 90 degrees - 72 degrees, which equals 18 degrees.
67.5 degrees
45o
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.
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.
The complement is 60 degrees.
Interior angle+exterior angle = 180 degrees
Since the sum of the two complement angles is 90⁰ , then the complement of a 60⁰ angle is a 30⁰ angle.
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
Any angle less than 90o will have a complement.
