Schindler's book is not easy to read; his prose is technical and his subject matter is abstruse. But it is also a joy to read.

Our solution: read more and see more movies. But the use of obtuse for something that one has difficulty penetrating has not escaped the criticism of some commentators. An acute angle is an angle-- well, let me just draw them first. Then it might start to make sense. So an acute angle will look something like that. I draw two rays that are coming from a common point. So the acute angle will be this angle right over here. I could also draw an acute angle, maybe an angle that's formed from the intersection of two lines.
This angle will be acute, and so will this angle. They're both acute angles. And we're going to see is acute angles are ones that are-- since I haven't defined right angles yet-- they're narrower. And what we're going to see is that they're smaller than right angles. Right angles are when the rays or the lines are going, I guess, in the-- I don't want to use the word, right, in my definition-- but if one is going horizontal, the other one will be going vertical.
So let me draw it with the rays first. So the right angle, this one's going from the left to the right. Then the other ray is going from the bottom to the top. This angle right over here is a right angle. And I could label it like that, as a traditional angle. But the general convention for labeling right angles is to put a little, kind of a half of a box right over there.
And that means that is a right angle. Or that if this is going left to right, this is going perfectly top to bottom, that this is in no way kind of-- I guess the best way to think about it and why it's called right is that this ray is completely upright, compared to this ray over here.
And let me draw it with some lines. So if I have one line like this and then I have another line like that, a right angle over here-- actually all of these would have to be right angles-- it would mean that this line is completely-- if this was the ground, this line is completely upright, relative to this line over here. So either of these, that's what a right angle means. And now that we've defined right angle, I can give you another definition for an acute angle.
An acute angle has a measure, or it's smaller, than a right angle. When you learn about radians and degrees, which are different ways to measure angles, you'll see that a right angle can be measured as 90 degrees. This over here is less than 90 degrees.
