Types of Angles and Angle Notation Explained

What forms an angle?

• Two parallel lines

• Two rays sharing an endpoint

• A single line bending

• Two intersecting circles

What is the shared endpoint of two rays in an angle called?

• Axis

• Vertex

• Midpoint

• Origin

How is an angle notated?

• Using two points

• Using a single point

• Using four points

• Using three points with the vertex in the middle

How is the vertex represented in angle notation?

• As the middle letter

• Not included in the notation

• As the last letter

• As the first letter

What does rotating a ray around its endpoint illustrate?

• The creation of a circle

• The measurement of an angle in degrees

• The division of space into equal parts

• The formation of a parallel line

What is a straight angle?

• An angle more than 180 degrees

• An angle of 180 degrees

• An angle less than 90 degrees

• An angle of 90 degrees

What is a right angle?

• An angle less than 90 degrees

• An angle more than 90 degrees

• An angle of 180 degrees

• An angle of 90 degrees

What defines an acute angle?

• An angle more than 90 degrees but less than 180 degrees

• An angle exactly 90 degrees

• An angle less than 90 degrees

• An angle of 180 degrees

What defines an obtuse angle?

• An angle of 180 degrees

• An angle of 90 degrees

• An angle less than 90 degrees

• An angle more than 90 degrees but less than 180 degrees

Which of the following is not a special type of angle discussed?
