WebTwo angles are Complementary when they. add up to 90 degrees (a Right Angle ) These two angles (40° and 50°) are Complementary Angles, because they add up to 90°: Notice that together they make a right angle. But the angles don't have to be together. These two are complementary because 27° + 63° = 90°. WebA right triangle ( American English) or right-angled triangle ( British ), or more formally an orthogonal triangle, formerly called a rectangled triangle [1] ( Ancient Greek: ὀρθόσγωνία, lit. 'upright angle'), [2] is a triangle in which one angle is a right angle (that is, a 90- degree angle), i.e., in which two sides are perpendicular.
