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.
What are 3 different kinds of triangles?
There are actually many different kinds of triangles. They are classified by both side lengths and angle measures. Angle Classifications: 1)Acute- all angels equal less than 90 degrees, unless they are all equal 2)Obtuse- at least one angel equals more than 90 degrees 3)Equiangular- all angels are equal, ie. 60 degrees 4)Right- one of the angels equal 90 degrees Side Length Classifications: 1)Isosceles- two sides are equal 2)Scalene- all side lengths are different 3)Equilateral- all side lengths are the same
How many degrees does two right angles have?
well, 1 right angle is equal to 90 degrees, when added up, its 180.
What kinds of symmetry do an isosceles trapezoid have?
Do you mean trapEzoid? An isosceles trapezoid is a four sided figure with only two opposite sides parallel. The base angles are equal and and the angles to the other parallel line are also equal. The degrees of the four angles added together equal 180. Check out <wikipedia.com> for more details.
What has to be true for two angles to be complementary?
Their measurements must equal 90° when added together. Supplementary is 180°.
