Measuring and Classifying Angles

What forms an angle?

• A single line bending at a point

• Two rays sharing a common endpoint

• Two circles intersecting each other

• Two lines intersecting at a common point

What is the vertex of an angle?

• The outer point of an angle

• The common endpoint of the rays forming the angle

• The point where two sides meet

• The longest side of the angle

How can a single angle be named using points?

• Using three points with the vertex in the middle

• Using any three points on the angle

• By the vertex point only

• By only the middle point

When multiple angles are present, how should they be named?

• Using the vertex point only

• Naming is not necessary

• Using any point on the angles

• Using three points with the vertex in the middle

What is the purpose of a protractor in angle measurement?

• To draw perfect circles

• To measure the length of the sides

• To determine the angle's vertex

• To measure the size of the angle
