Right angles are fundamental in Euclid's Elements. They are defined in Book 1, definition 10, which also defines perpendicular lines. Definition 10 does not use numerical degree measurements but rather touches at the very heart of what a right angle is, namely two straight lines intersecting to form two equal and adjacent angles. The straight lines which form right angles are called perpendicular. Euclid uses right angles in definitions 11 and 12 to define acute angles (those sm… WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. … patricia bealleWebThe interior angles of triangle is $180^°$.
