If the sum of the measures of two angles is ninety degrees then the angles are what?
Complementary
How many degrees do the measures of complementary angles add up to?
Ninety Degrees
What is the angle called that measures exactly ninety degrees?
A right angle is exactly 90 degrees.
What two angles are----if the sum of their measures in ninety?
Complementary
What is the rectangle size of angles?
Ninety degrees.
When two angles added together equal ninety degrees they are said to be?
Two angles are called complementary angles if the sum of their degree measurements equals 90 degrees. One of the complementary angles is said to be the complement of the other.
When the sum of two angles are ninety degrees?
They are complementary.
What is complementry angles?
Two angles whos sum equals ninety degrees
Why must a right triangle have two acute angles?
A right angle must have two acute angles because since one angle is ninety degrees, than the other two must equal ninety degrees. To make ninety degrees with two angles, both of them must be acute, or less than 90 degrees (each).
How many degrees are there in 3 right angles?
270. A right angle is ninety degrees.
How is it call a triangle with two angles that are complementary?
Complementary angles add up to ninety degrees. Triangles must hold 180. Taking these facts together, think of this: you have two angles in a triangle where they add up to ninety. This means that the other angle in the triangle must hold the other ninety. I'm not going to answer your question, but I'll pose you the question you should have asked: What is a triangle called when it has one angle that is exactly ninety degrees?
What are complementary angles always?
Complementary angles are angles that always add to 90° (ninety degrees). They are usually adjacent to each other, however in theory do not have to be. An example is: Angle "a" is 38°, and is situated next to, or adjacent to Angle "b" which is 52°. In this case, both angles (38 and 52) sum to ninety degrees, which means Angle a is complementary with, or to, Angle b. Another example is: Angle "a" is 56°, and is situated next to, or adjacent to Angle "b" which is 43°. In this case, both angles (56 and 43) do not sum to ninety degrees, which means Angle a is not complementary with, or to, Angle b. Complementary angles are studied in conjunction with supplementary angles (angles which sum to 180°) and angles at a point (angles which sum to 360°). Note: There does not have to be only two angles (however this is the minimum requirement, because a ninety degree angle can't have a complement of 0°). There can be three, five, ten, twenty, or whatever number of angles you wish (remember, you are not limited to there being ninety one degree angles because angles can have decimal points too, i.e. 56.32°). Hope this helped.
