Something at a sharp angle, slant, or incline can be described as angled. An angled ramp makes skateboarding more fun.
The roof of your house is probably angled, and so is the ramp of a parking garage and the blade of a chef's knife. Sports reporters are fond of describing certain moves as angled, too, like an angled basketball shot or an angled football run. The adjective angled comes from angle, "space between intersecting lines," from the Latin angulus, "an angle or a corner."
