no it isnt
Right angles are always 90 degrees, (or pi/2 radians if you're into such things) so there isnt really anything to calculate. You can check that a triangle contains a right angle by verifying it obeys pythagoras theorem, x2 + y2 = h2 where x and y are the lengths of the two other sides and h is the length of the longest side (the hypotenuse). If this is the case, the right angle is the one opposite that side, if not, the triangle doesn't contain a right angle.
if something isnt the right shape to do a job, it can't do that job.
i really dont know...isnt it normal to eat bloody tampons
ice cream dosen't have a physical shape since it isnt really solid. you can compact it and make it a cube, a sphere, a triangle or whatever, but id say since adventualy it turns liquid it has no physical true shape
It has to be made properly in order to do what it's supposed to do.
There isnt one
Honestly, it isnt. Its a waste of time
It has less than three sides.
