ComplementComplementary angles sum to 90o, thus: The complementary angle of 45o is 90o - 45o = 45oSupplementSupplementary angles sum to 180o, thus: The supplementary angle of 45o is 180o - 45o = 135o

90o. Let A be the size of the smallest angle. Then the three angles are A, A & 2A. The sum of the angles in a triangle is 180o, thus: A + A + 2A = 180o 4A = 180o A = 45o So the largest angle is 2A = 2 x 45o = 90o.

360 *********************** The correct answer is 180 degrees. A right-angle triangle has 3 corners of 90o + 45o + 45o = 180o
The sum of all three angles of a triangle are 180o; if two are 24o and 111o then the thrid is: third_angle = 180o - 24o - 111o = 45o

Each interior angle of an octagon is 135o. The sum of the exterior angles of a polygon is 360o. A regular octagon has equal angles, thus: 8 x exterior_angle = 360o ⇒ exterior_angle = 360o ÷ 8 = 45o The interior and exterior angles of a polygon are supplementary, that is sum to 180o. interior_angle + 45o = 180o ⇒ interior_angle = 180o - 45o = 135o.

Draw a right angle (90o). Bisect the right angle and there will be two 45o angles. Bisect one of the 45o angles and there will be one 45o angle and two 22.5o angles. A 67.5o angle includes the 45o angle and the 22.5o angle next to it, totaling 67.5o.
