Geometry Terms

1. What is a specific location in space with no size or shape?

Point

Plane

Line

Circle

In geometry, a point is defined as a specific location in space that has no size or shape. It is considered to be one of the basic building blocks of geometry, along with lines, planes, and shapes.

2. What is the term for part of a line that extends indefinitely in one direction?

Angle

Ray

Curve

Line segment

A ray is a part of a line that starts at a point and extends indefinitely in one direction. A line segment is a part of a line with two endpoints. A curve is a continuous, smooth, flowing line without sharp angles. An angle is formed by two rays with a common endpoint.

3. What is a never-ending straight path extending in two directions?

Triangle

Circle

Curve

Line

A line is a geometric figure that extends infinitely in two directions, while a curve is not straight and does not extend infinitely in two directions. A circle is a closed curve, and a triangle is a polygon with three sides.

4. What is formed by two rays that have the same endpoint?

Circle

Line

Vertex

Angle

When two rays have the same endpoint, they form an angle. A line is formed by an infinite number of points extending in two opposite directions. A circle is a shape formed by all points equidistant from a center point. A vertex is a point where two lines meet to form an angle.

5. What is the name of the common endpoint of two rays that form an angle?

Node

Endpoint

Vertex

Intersection

In geometry, the common endpoint of two rays that form an angle is called the vertex. The vertex is where the two rays meet to form the angle.

Explanation

In geometry, the common endpoint of two rays that form an angle is called the vertex. The vertex is where the two rays meet to form the angle.

6. What are the two rays that make up an angle called?

Degrees

Angles

Vertices

Sides

In geometry, the two rays that make up an angle are called sides. Angles are the space between two intersecting lines, vertices are the meeting point of lines or edges, and degrees are units of measurement for angles.

7. What is the common unit of measure for angles? (Also the name of a deodorant brand).

Gradian

Minute

Radian

Degree

Degrees are the most commonly used unit to measure angles, with each full circle consisting of 360 degrees. Radians, Gradians, and Minutes are less frequently used units for measuring angles.

8. What is the tool used to measure and draw angles?

Ruler

Protractor

Compass

Level

A protractor is specifically designed for measuring and drawing angles, while a ruler is used for measuring straight lengths, a compass is used for drawing circles, and a level is used for determining horizontal or vertical alignments.

9. What is the type of angle that measures exactly 90 degrees?

Straight Angle

Right Angle

Obtuse Angle

Acute Angle

A right angle is exactly 90 degrees, forming an 'L' shape. An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees, and a straight angle is exactly 180 degrees.

Explanation

A right angle is exactly 90 degrees, forming an 'L' shape. An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees, and a straight angle is exactly 180 degrees.

10. What is the type of angle that measures exactly 180 degrees?

Straight Angle

Reflex Angle

Obtuse Angle

Acute Angle

A straight angle measures exactly 180 degrees, forming a straight line. An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a reflex angle is greater than 180 degrees but less than 360 degrees.

Explanation

A straight angle measures exactly 180 degrees, forming a straight line. An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a reflex angle is greater than 180 degrees but less than 360 degrees.
