They are known as complementary angles.
Supplementary angles are two angles that add up to 180 degrees. They are only equal if they both equal 90 degrees.
A rhombus has two equal opposite acute angles and two opposite equal obtuse angles and the four angles add up to 360 degrees
There are 3 angles in an isosceles triangle and they add up to 180 degrees Two of the angles are of equal measurement
The two angles are complementary, seeing as they add up to equal 90 degrees.
An isosceles trapezoid has two equal obtuse angles and two equal acute angles that all add up to 360 degrees
Two angles that are equal to 90 degrees are Complimentary.
It has two equal acute angles and two equal obtuse angles which all add up together to 360 degrees
Yes it has 2 equal opposits acute and 2 equal opposite obtuse angles and they add up to 360 degrees
Two and the three interior angles add up to 180 degrees
That depends on the shape of the trapezoid as for example if it is an isosceles trapezoid then it will have two equal acute angles and two equal obtuse angles that all add up to 360 degrees.
Suppelmentry angles are two angles that add up to equal 180 degrees. So yes, 2 right angles (90 degrees each) would be supplementry
They work out as two equal opposite angles of 120 degrees and two equal opposite angles of 60 degrees.
