Exploring Lines and Angles

What defines a point in geometry?

• A continuous set of points

• A location with exact coordinates

• A path with two endpoints

• A part of a line with one endpoint

Which geometric term describes a straight path that extends infinitely in both directions?

• Point

• Line

• Line segment

• Ray

What is a line segment?

• A part of a line with two endpoints

• A line that extends indefinitely in one direction

• A complete line with two endpoints

• A part of a line that stops at one point

What is the correct way to name a ray?

• Using the endpoint last

• Using any point on the ray

• Using the endpoint first

• Using the farthest point

How is an angle named using three points?

• The middle point is the shared endpoint

• The first point is the shared endpoint

• The last point is the shared endpoint

• All points are at the endpoints

Which angle is exactly 90 degrees?

• Acute angle

• Obtuse angle

• Straight angle

• Right angle

What type of angle is less than 90 degrees?

• Straight angle

• Right angle

• Acute angle

• Obtuse angle

Which angle is more than 90 degrees but less than 180 degrees?

• Obtuse angle

• Straight angle

• Right angle

• Acute angle

What is a straight angle equivalent to?

• 90 degrees

• Less than 90 degrees

• More than 90 degrees

• 180 degrees

Can an angle be both acute and obtuse at the same time?

• No, unless it is a straight angle

• Yes, if it is a right angle

• No, it can only be one type

• Yes, in non-Euclidean geometry
