Finish this test and enjoy it! You can do it.

• 1.

### What is the name of this figure?

• A.

Square

• B.

SpHere

• C.

Cube

• D.

Rectangular prism

C. Cube
Explanation
The correct answer is cube because a cube is a three-dimensional shape with six equal square faces. It is a type of rectangular prism, but specifically, all of its faces are squares.

### What is the name of this figure?

• A.

SpHere

• B.

Circle

• C.

Sun

• D.

Cube

A. SpHere
Explanation
A sphere is a three-dimensional geometric shape that is perfectly round in shape, with all points on its surface equidistant from the center. It does not have any faces, edges, or vertices. The figure in the question appears to be a sphere as it is round and does not have any flat surfaces or corners. A circle is a two-dimensional shape, while a sun and a cube have different shapes and characteristics that do not match the figure in the question.

### The _______________________ are straight, intersecting lines.

perpendicular lines
Explanation
Perpendicular lines are straight lines that intersect each other at a 90-degree angle.

• 4.

### What is the name of this line?

• A.

Line

• B.

Line segment

• C.

Intersecting lines

• D.

Perpendicular lines

B. Line segment
Explanation
A line segment is a part of a line that is bounded by two distinct endpoints. It is different from a line as it has a definite length and can be measured. In this question, the given figure represents a line segment because it has two distinct endpoints and does not extend infinitely in both directions like a line. Therefore, the correct answer is line segment.

### What is the name of this figure?

• A.

Triangle

• B.

Square

• C.

Square pyramid

• D.

Point

C. Square pyramid
Explanation
A square pyramid is a three-dimensional figure that has a square base and four triangular faces that meet at a single point called the apex. In this case, the figure in question is a square pyramid as it has a square base and four triangular faces.

### These lines never intersect. They are called ____________________.

parallel lines
Explanation
Parallel lines are lines that never intersect, meaning they do not cross or touch each other at any point. They are always at the same distance apart and have the same slope.

### What is the name of this figure?

• A.

Rectangular prism

• B.

Cube

• C.

Ruler

• D.

Rectangle

A. Rectangular prism
Explanation
A rectangular prism is a three-dimensional shape that has six rectangular faces. It is also known as a rectangular cuboid. The figure in the question is a three-dimensional shape with six rectangular faces, so it can be correctly identified as a rectangular prism.

### What is the name of the point northwest from Point C?

• A.

Point D

• B.

Point A

• C.

Point E

• D.

Point B

A. Point D
Explanation
The point northwest from Point C is named Point D.

Rate this question:

### An _________________________ is a line that crosses another line and never stops.

intersecting line
Explanation
An intersecting line is a line that crosses another line and never stops. It continues indefinitely in both directions, intersecting the other line at a specific point. This type of line can be found in geometry, where it is used to determine angles and relationships between different lines and shapes. The term "intersecting" implies that the two lines cross each other at a certain point, rather than just touching or being parallel to each other.

• 10.

### What is the name of this figure?

• A.

SpHere

• B.

Cone

• C.

Cylinder

• D.

Cube

C. Cylinder
Explanation
The correct answer is cylinder because a cylinder is a three-dimensional shape that has two circular bases and a curved surface connecting the bases. It does not have any flat faces like a cube or cone, and it is not a perfectly round shape like a sphere.
