Answer and Step-by-step explanation:
These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.
They are functions revealing the shape of a right triangle.
Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.
Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.

Answer:
In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.
The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon's vertices(singular: vertex) or corners.
So, if a shape has points where two edges meet, it is indeed a polygon. Some examples include: Equilateral Triangles, Squares, Regular Pentagons, Regular Hexagons, Regular Heptagons, and Regular Octagons.
The match that can be made of these definitions are as follows
a. Space is the set of all points, lines, and planes. This definition is not understandable.
b. A radius is a chord containing the center of the circle. This definition is not accurate.
c. An angle is the union of two distinct rays, this definition is not concise.
<h3>What is space?</h3>
This is the term that is used to mean a continuous area or an expanse that is not occupied. The space is the free available area. When it is defined in this way, it would make the understanding of the word to be more possible and easier for the learner.
<h3>What is a radius?</h3>
This is used to refer to a straight line that is drawn from the center of a circle in such a way that it would have to touch the circumference of that particular circle.
<h3>What is an angle?</h3>
This is the space that is formed when two lines that are intersecting themselves at a particular point. When they meet they would have to form an angle.
