The term complimentary attitude refers to the two non-precise angles in a precise triangle. on account that all of the angles in a triangle upload to one hundred eighty stages, no depend what style it is, then a precise triangle's different 2 angles ought to function to ninety stages additionally (by way of fact one hundred eighty - ninety = ninety). So, ninety - 75 = 15 you have a precise attitude (ninety deg), a non-precise attitude (75 deg) and a complimentary non-precise attitude (15 deg). on account that those 2 angles are so an prolonged way aside, it shows that the leg of the triangle coming off the 75 diploma attitude is somewhat short and the single coming off the 15 deg attitude is somewhat long (almost an identical length by way of fact the hypotenuse)
