1.   A piece of paper may represent an undefined term in Geometry that is called __________.

• Angle

• Line

• Point

• Plane

Points A, B, and C are said to be collinear. Which of the following is NOT true?  

•  Points A and B are on the same line

• Points A and C are on the same line

• Points A, B and C are on the same line

• Points A, B and C are not on the same line

It is a term in Geometry described as a flat surface having infinite length and width but no thickness.  

• Angle

• Line

• Point

• Plane

It is a part of a line that has two endpoints.

• segment

• ray

• solid line

• broken line

It is a union of two non-collinear rays with a common endpoint. 

• Angle

• Line Segment

• Point

• Ray
