Geometry is an essential part of mathematics that assists in studying the size, shapes, and dimensions of things or objects. In Flat Geometry, Squares, circles, and triangles are some of the simple forms of shapes whereas Cubes, cylinders, cones, and spheres are simple shapes in solid geometry. This quiz has been designed to test your basic Geometry Vocabulary and definitions. So, let's try out the quiz. All the best!

• 1.

### What is the area of a square with side 5

• A.

25 cm

• B.

25 cm^2

• C.

20 cm

• D.

None of the above

B. 25 cm^2
Explanation
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.

### What is the height of a triangle with an area of 30 cm^2 and a base of 10 cm?

• A.

6 cm

• B.

3 cm

• C.

300 cm

• D.

None of the above

A. 6 cm
Explanation
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.

### What is the best description of a point?

• A.

Straight path that has no thickness and extends forever

• B.

Names a location, has no size

• C.

flat surface that has no thickness and extends forever

• D.

Vertical point

B. Names a location, has no size
Explanation
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.

### What is the best description of a plane?

• A.

straight path that has no thickness and extends forever

• B.

Names a location, has no size

• C.

Flat surface that has no thickness and extends forever

• D.

A thick surface

C. Flat surface that has no thickness and extends forever
Explanation
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.

### What is the best description of a line?

• A.

Straight path that has no thickness and extends forever

• B.

Names a location, has no size

• C.

flat surface that has no thickness and extends forever

A. Straight path that has no thickness and extends forever
Explanation
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.

### What is the definition of a postulate?

• A.

A statement that is accepted as true without proof

• B.

A part of a line that starts at an endpoint and goes on forever

• C.

a statement that has been proven

• D.

Part of a line consisting of two points and all points between them

A. A statement that is accepted as true without proof
Explanation
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.

### What is the definition of coplanar?

• A.

A point at the end of a segment or the starting point of a ray

• B.

Points that lie on the same line

• C.

Points that lie on the same plane

• D.

Part of a line consisting of two points and all points between them

C. Points that lie on the same plane
Explanation
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.

### What is the definition of collinear?

• A.

A part of a line that starts at an endpoint and goes on forever

• B.

A part of a line that starts at an endpoint and goes on forever

• C.

Points that lie on the same plane

• D.

A point at the end of a segment or the starting point of a ray

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

### What is the definition of a segment?

• A.

Part of a line consisting of two points and all points between them

• B.

A point at the end of a segment or the starting point of a ray

• C.

A statement that is accepted as true without proof

• D.

A statement that has been proven

A. Part of a line consisting of two points and all points between them
Explanation
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.

### What is the definition of a ray?

• A.

A point at the end of a segment or the starting point of a ray

• B.

A part of a line that starts at an endpoint and goes on forever

• C.

Part of a line consisting of two points and all points between them

• D.

A statement that is accepted as true without proof

B. A part of a line that starts at an endpoint and goes on forever
Explanation
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.
