90 degrees is a right angle
0<theta<90 is acute
90<theta<180 is obtuse
180 degrees is a straight line
0 degrees is a straight line
only the 90 degree angle is a right angle. All the others are left wing liberal angles
only the zero and the 180 degree angles are straight lines. all the others are LGBT angles
you could go higher than 180 though, or negative angles less than zero
but for triangles, angles are limited to the range 0<angle<180
but if you go beyond those limits
there are an infinite number of right (perpendicular) angles
..., -270, -90, 90, 270, 450, ...
an infinite number of acute and obtuse (although that's already true for just the 0 to 180 range)
an infinite number of straight lines: ...-360, -180, 0, 180, 360, 540, ...
If it's getting too hot for you this summer with temperatures in the 100+ degree range
give up on stopping global warming and
just go sit in a corner, where the temperature is always just "right" with 3 right angles as the 3 walls come together all perpendicular to each other
A university professor, a guy like Dr. Sheldon Cooper, once said he had 90 academic degrees. People found that hard to believe, but it's true if you look at it from the "right" perspective, from the "right angle" You have to look at it from the "right angle," as any other angle is the wrong angle. and two wrongs don't make a right, so don't add 45 to 45 to get a right angle, or wait? that works. 2 wrongs make a right?
obtuse means stupid or dull, not sharp, like a blade with an angle of nearly flat which can't cut it, just can't cut it.
acute doesn't mean a "cute" or a "cutie" but means acute as in sharp, bright, intelligent, sharp cutting, a blade that cuts. get an acute enough blade and it's razor sharp, cuts to the bone, an angle between 90 and 0
There you have it, more than you ever wanted to know about acute, obtuse and right, Unless you want to go fishing, and angling for bigger fish. AG (AnGle?) Garland has been angling for a SCOTUS job for years. Don't give up. Keep angling and you'll get there. Some day. Maybe.
