Answer:
a.The points D, P and X lies in the interior of the circle. The point R, Q, N lie on the circle. The centre O of the circle always lies in the interior of the circle.
b.Triangular region is the region inside the triangle that is, inside the boundary of the triangle including boundary.
b.A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero size (that is, zero length, zero width, and zero height).
d.Given any three non-collinear points, there is exactly one plane through them. A plane can be named by a capital letter, often written in script, or by the letters naming three non-collinear points in the plane. For example, the plane in the diagram below could be named either plane ABC or plane P .
e.Plane M has for sides, so we can rename plane M as a quadrilateral.
