What is a branch of mathematics that deals with points, lines, planes, solids and examines their properties?
Correct Answer
B. Geometry
Explanation
Geometry is the branch of mathematics that deals with points, lines, planes, and solids and examines their properties. It explores the relationships between these geometric objects and studies concepts such as shape, size, angles, and dimensions. Geometry is used in various fields such as architecture, engineering, art, and physics to understand and analyze the physical world.

What is a set of points that form a straight path that goes on forever in both directions?
Correct Answer
C. Line
Explanation
A line is a set of points that form a straight path that goes on forever in both directions. It has no endpoints and extends infinitely in both directions. It is different from a line segment, which has two endpoints and is a finite portion of a line. A point is a single location in space, while skew refers to lines that do not intersect and are not parallel. Therefore, the correct answer is line.
3.
What is a part of a line defined by 2 endpoints?
Correct Answer
C. Line Segment
Explanation
A line segment is a part of a line that is defined by two endpoints. It is the portion of the line that lies between these two points. Unlike a line, which extends infinitely in both directions, a line segment has a finite length and can be measured. Therefore, a line segment is the correct answer to the question.
4.
What are intersecting lines that cross each other and form right angles?
Correct Answer
A. Perpindicular
Explanation
Perpendicular lines are lines that intersect each other and form right angles. This means that they cross each other at a 90-degree angle. The other options, such as intersecting lines, rays, and skew lines, do not necessarily form right angles when they intersect. Therefore, the correct answer is perpendicular.
5.
What is a set of points that have infinite legnth and width?
Correct Answer
D. Plane
Explanation
A plane is a two-dimensional flat surface that extends infinitely in all directions. It has infinite length and width, as it has no boundaries or edges. Unlike lines, which are one-dimensional and have infinite length but no width, a plane has both length and width. Therefore, a set of points that have infinite length and width would be best described as a plane.
6.
What is a point of a line that has an endpoint and continues forever in one direction?
Correct Answer
A. Ray
Explanation
A ray is a point of a line that has an endpoint and continues forever in one direction. Unlike a line segment, which has two endpoints and a specific length, a ray extends infinitely in one direction. A line, on the other hand, extends infinitely in both directions. Parallel lines are lines that never intersect and are always the same distance apart. Therefore, the correct answer is ray.
7.
What are two or more lines in the same plane that will never touch.
Correct Answer
C. Parallel Lines
Explanation
Parallel lines are two or more lines in the same plane that will never touch or intersect each other. They maintain the same distance between each other at all points, extending indefinitely in both directions. This property of parallel lines is a fundamental concept in geometry and has various applications in fields such as architecture, engineering, and physics.
8.
What are lines that cross each other?
Correct Answer
A. Intersecting
Explanation
Lines that cross each other are called intersecting lines.
9.
What are lines that are not in the same plane?
Correct Answer
B. Skew
Explanation
Skew lines are lines that do not lie in the same plane. Unlike parallel lines, which never intersect, skew lines are non-parallel and do not lie in the same plane. They are also different from rays, which have a starting point and extend infinitely in one direction. Therefore, the correct answer is skew.
10.
What is an exact Location in space?
Correct Answer
B. Point
Explanation
An exact location in space refers to a specific position that has no dimensions or size. It is represented by a single point, which has no length, width, or depth. A point is the most fundamental element in geometry and is used to define other geometric shapes and objects. It is the only option provided that accurately represents an exact location in space without any extent or direction.
