(Drag the points) Right Angled Triangle WebIsosceles right triangle: The following is an example of a right triangle with two legs (and their corresponding angles) of equal measure. Isosceles obtuse triangle: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.

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. So tan(90) … WebA right triangle is triangle with an angle of 90 degrees (pi/2 radians).
