Remember all those pesky geometry classes in high school? Then you'll remember measuring the angle or space between two intersecting lines in degrees. If you recall that a right angle measures ninety degrees, give yourself a bonus.
Angle can also mean a biased way of looking at or presenting something. Talk radio stations, for example, often discuss current events with a "political angle." On a far more peaceful note, to angle also means simply to fish, both in the literal sense of trying to catch a fish on a hook or in the metaphorical sense of trying to subtly obtain something without being seen to do so directly, as in, "I'm going to angle for a promotion at work."
Primary Meanings of angle
1. 
nv 
the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians
move or proceed at an angle

2. 
nv 
a biased way of looking at or presenting something
present with a bias

3. 
v 
fish with a hook
