Two angles that equal 90 degrees?
complementary angles.
What are two angles that the sum of their measures equal 90 degrees?
They are complementary angles
What angles combine to equal 90 degrees?
Angles combining to equal 90 degrees are known as complementary angles.
What has two sides equal lengths and all angles equal 90 degrees?
A rectangle.
If one the angles of a right triangle is 30 degrees what are the other two angles?
Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==
When the sum of two angles equal exactly 90 degrees?
If you mean "Does the sum of two angles equal exactly 90 degrees?" it is yes.
If two angles are supplementary are the sum of their measures 90?
Supplementary means the sum of two angles equal to 180 degrees. The Sum of 90 degrees would be complimentary, where the sum of two angles equal to 90 degrees.
Two angles that equal 90 degrees?
complementary angles.
Are supplementary angles equal?
Supplementary angles are two angles that add up to 180 degrees. They are only equal if they both equal 90 degrees.
How many different crystals are crystals classified into?
Seven. They are: Cubic - all angles 90 degrees, all sides equal length Trigonal - all angles 90 degrees, two sides equal and the third unequal Orthorhombic - all angles 90 degrees, no sides equal Hexagonal - two angles 90 degrees and one angle 120 degrees, two sides unequal and the third unequal Trigonal - all angles equal but not 90, all sides equal Monoclinic - two angles 90, one more than 90, and no sides equal Triclinic - no angles equal, no sides equal For a graphical representation of these, see http://en.wikipedia.org/wiki/Crystal_system#Classification_of_lattices
What are two angles that add to equal 90 degrees?
They are known as complementary angles.
What are two angles that the sum of their measures equal 90 degrees?
They are complementary angles
What angles combine to equal 90 degrees?
Angles combining to equal 90 degrees are known as complementary angles.
What is the definition of corresponding angles?
any two or more angles that equeal 90 degrees supplementary angles are when two or more angles equal 180 degrees
Are two angles of a rectangle equal?
Yes, because a rectangle has 4 equal interior angles of 90 degrees.
How much degrees are two right angles?
One right angle is equal to 90 degrees, or a vertical line extending from the o degree plane. Therefore, two right angles, presumably side to side, would have 180 degrees, since together the would be supplementary angles. Supplementary angles are two angles which combine to from 180 degrees, and 90 plus 90 would equal 180 degrees. Look at angle DBE and at angle EBC. Each are 90 degree angles, or right angles, and together equal 180 degrees.
What has two sides equal lengths and all angles equal 90 degrees?
A rectangle.
