1. What is a line segment?
- AA line with one endpoint
- BA line with two endpoints
- CA line extending infinitely
- DA line with no endpoints

3. In a polygon, the line segments that make up the boundary are called its:
- AVertices
- BSides
- CDiagonals
- DAngles

Answer: B) Sides
The line segments forming the boundary of a polygon are called its sides; the corners are vertices.
5. Ramesh draws ray PQ and ray QP using the same two points P and Q. Which statement is correct?
- ARay PQ and ray QP are exactly the same ray
- BRay PQ and ray QP are different rays because they start at different points and point in opposite directions
- CBoth rays have two endpoints
- DNeither PQ nor QP is a ray
Show answer
Answer: B) Ray PQ and ray QP are different rays because they start at different points and point in opposite directions
A ray is named by its starting point first. Ray PQ starts at P and goes toward Q, while ray QP starts at Q and goes toward P. They start at different points and head in opposite directions, so they are different rays.
