convex of a polygonal line

if it lies on each side of each of its segments

polygonal line is closed if

its initial and its terminal points coincide

polygonal region

the closed polygonal line will be the boundary

Semicircle

If AB is a diameter of this circle and H is one of the half-planes determined by AB, the set of all points on this circle that belong to H together with the points A and B

minor arc

the set of all points on the circle C(O,r) in the interior of a central angle ∠AOB together with the points A and B

major arc

the set of all points on C(O,r) which do not belong to the minor arc, together with the points A and B

proportion of (pairs of) segments

segments are proportional if their lengths patronizes like *a**:**b**=**c**:**d*.

Cosine of an angle

in a right triangle, the ratio of the side adjacent to the angle and the hypotenuse
