Answer Key
Section A — Multiple Choice Questions
- (C) $2$
- (B) $1$
- (B) meet at a point
- (B) no size
- (B) vertex
Section B — Short Answer (2 marks)
- $2$.
- $1$.
- The vertex.
- Rays.
Section C — Short Answer (3 marks)
- A line segment.
- A ray.
- At the vertex.
- No.
Section D — Long Answer (5 marks)
- Point: an exact location with no size; line segment: a straight path with two endpoints; ray: starts at one point and goes on forever one way; angle: formed by two rays meeting at a vertex.
- The vertex; a ray has $1$ endpoint, a line segment has $2$.
