16 a half of a circle or of its circumference.
17 triangle is a simple closed curve or polygon which is created by three line-segments.quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices. Other names for quadrilateral include quadrangle and tetragon.

16.In mathematics, a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180°. It has only one line of symmetry.
17.A triangle is a simple closed curve or polygon which is created by three line-segments. ... On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
