convex angle造句

• Flow can expand around either a sharp or rounded corner equally, as the increase in Mach number is proportional to only the convex angle of the passage ( ? ).
• Any polygon must have at least three convex angles, because the total exterior angle of a polygon is 2?, the convex angles contribute less than ? each to this total, and the concave angles contribute zero or negative amounts.
• Any polygon must have at least three convex angles, because the total exterior angle of a polygon is 2?, the convex angles contribute less than ? each to this total, and the concave angles contribute zero or negative amounts.
• This follows by a simple double counting argument involving the Euler characteristic : as each face but the outer one is a pseudotriangle, with three convex angles, the pseudotriangulation must have 3 " f "  " 3 convex angles between adjacent edges.

• When defining or drawing a central angle, in addition to specifying the points A and B, one must specify whether the angle being defined is the convex angle ( < 180 & deg; ) or the reflex angle ( > 180 & deg; ).
