The best description of a line is a straight path that has no thickness and extends forever. A line is a fundamental geometric concept that represents the shortest distance between two points. It is infinitely long in both directions and has no width or depth. A line can be visualized as a perfectly straight and infinitely thin object. This description accurately captures the essential characteristics of a line.

A plane is best described as a flat surface that has no thickness and extends forever. This means that it is a two-dimensional object with no depth and continues infinitely in all directions. It does not have any curves or angles and is completely flat. This description accurately captures the defining characteristics of a plane.

A point is best described as a location without any size. It is a precise position in space that is represented by a dot. Unlike lines or surfaces, a point has no dimensions or thickness. It is simply a specific point in space that can be identified and named.

A segment is defined as a part of a line that is formed by two distinct points and includes all the points that lie between them. In other words, it is a portion of a line that has a definite beginning and end point. This definition distinguishes a segment from a ray, which has only one endpoint and extends infinitely in one direction.

The definition of coplanar is when points lie on the same plane. In geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions. If points are coplanar, it means they all lie on this same flat surface. This is different from points that lie on the same line, which means they are all on a straight path, or a segment which refers to a part of a line consisting of two points and all the points between them.

A postulate is a statement that is accepted as true without proof. It is an assumption or a basic principle that is taken to be true in a particular context or system. Postulates serve as the foundation for reasoning and deduction in various fields, such as mathematics and logic. They are considered to be self-evident or intuitively true, and they provide a starting point for building logical arguments and proving theorems.

The area of a square is calculated by multiplying the length of one of its sides by itself. In this case, the side of the square is given as 5 cm. Therefore, the area of the square can be found by multiplying 5 cm by 5 cm, which equals 25 cm^2.

A ray is defined as a part of a line that starts at an endpoint and extends infinitely in one direction. Unlike a line segment, which has two endpoints and a specific length, a ray has only one endpoint and continues indefinitely in one direction. This means that a ray has no end point and goes on forever in one direction. Therefore, the given answer accurately describes the definition of a ray.

The height of a triangle can be calculated using the formula: height = (2 * area) / base. In this case, the area is given as 30 cm^2 and the base is given as 10 cm. Plugging these values into the formula, we get: height = (2 * 30 cm^2) / 10 cm = 60 cm^2 / 10 cm = 6 cm. Therefore, the height of the triangle is 6 cm.

The definition of collinear is a part of a line that starts at an endpoint and goes on forever.
