Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- ray; [Image] (You should always name a ray with the endpoint letter first.)
- line; [Image] (The arrows don't extend in both directions.)
- line segment; [Image] (There is an arrow that extends in one direction.)
- ray; [Image] (correct)
A: ray; [Image]

Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- angle; ∠EDB (Incorrect. If you use a three letter name for an angle, the vertex should be the middle letter.)
- angle; ∠D (Incorrect. Name the angle with its vertex letter.)
- angle; ∠B (Incorrect. Name the angle with its vertex letter.)
- angle; ∠E (correct)
A: angle; ∠E

Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- angle; ∠Y (Incorrect)
- line; [Image] (It is not a line, because it doesn't extend with arrows.)
- ray; [Image] (A ray extends in one direction with an arrow.)
- line segment; [Image] (correct)
A: line segment; [Image]

Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- ray; [Image] (It is a ray, but name it with the vertex letter first.)
- line; [Image] (This figure does not extend in both directions, so it is not a line.)
- line segment; [Image] (This figure extends in one direction. It is not a line segment.)
- ray; [Image] (correct)
A: ray; [Image]

Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- line segment; [Image] (The figure extends in two directions. A line segment ends.)
- line; [Image] (correct)
- angle; ∠X (Incorrect. There is a better name for that figure.)
- ray; [Image] (The figure extends in both directions, not just one.)
A: line; [Image]

Q: Identify the figure as a line, a ray, a line segment, or an angle. Then name the figure using the given points.

[Image]
- line; [Image] (correct)
- line segment; [Image] (The figure extends in both directions, so it is a line, not a line segment.)
- ray; [Image] (The figure extends in both directions, not just in one direction.)
- angle; ∠B (Incorrect)
A: line; [Image]

Q: Solve the problem.

Draw the segment whose endpoints are P and Q. Name the segment in two ways.

[Image]
- [Image] PQ or QP (Good line segment, but you need a line segment symbol above the names.)
- [Image] [Image] or [Image] (You made a ray. Make a line segment instead.)
- [Image] [Image] or [Image] (You made a line. Make a line segment that ends instead.)
- [Image] [Image] or [Image] (correct)
A: [Image] [Image] or [Image]

Q: Solve the problem.

Draw the line which passes through S and T. Name the line in two ways.

[Image]
- [Image] [Image] or [Image] (This is a good line, but the names need to have double arrow line symbols above them.)
- [Image] [Image] or [Image] (You made a line segment. Make a line that extends with arrows.)
- [Image] [Image] or [Image] (correct)
- [Image] [Image] or [Image] (You made a ray. Make a line that extends in both directions.)
A: [Image] [Image] or [Image]

Q: Solve the problem.

Draw the ray with endpoint M . Name the ray.

[Image]
- [Image] [Image] (This is a line. Make a ray instead.)
- [Image] [Image] (This is the correct ray, but the name is wrong.)
- [Image] [Image] (This is a line segment. Make a ray instead.)
- [Image] [Image] (correct)
A: [Image] [Image]

Q: Solve the problem.

Name the line in seven different ways.

[Image]
- n, [Image], [Image], [Image], [Image], [Image], [Image] (Incorrect. Only use two letters when writing the name of a line.)
- n, [Image], [Image], [Image], [Image], [Image], [Image] (Incorrect. Make sure all your line names have double arrow symbols above them.)
- n, [Image], [Image], [Image], [Image], [Image] [Image] (correct)
- n, [Image], [Image], [Image], [Image], [Image], [Image] (Incorrect. Make sure all your line names have double arrow symbols above them.)
A: n, [Image], [Image], [Image], [Image], [Image] [Image]

Q: Name the angle in three different ways.

[Image]
- ∠XYZ, ∠ZXY, ∠XZY (Angle names should have the vertex letter in the middle always.)
- ∠XYZ, ∠ZYX, or ∠Y (Good Job!)
- ∠Y, ∠ZXY, or ∠ZYX (Angle names must have the vertex letter in the middle.)
A: ∠XYZ, ∠ZYX, or ∠Y

Q: Solve the problem.

Name the line in seven different ways.
[Image]
- m, [Image], [Image], [Image], [Image], [Image], [Image] (Incorrect. Make sure all your line names have double arrow symbols above them.)
- m, [Image], [Image], [Image], [Image], [Image], [Image] (Incorrect. Make sure all your line names have double arrow symbols above them.)
- m, [Image], [Image], [Image], [Image], [Image] [Image] (correct)
- m, [Image], [Image], [Image], [Image], [Image], [Image] (Only use two letters when naming lines.)
A: m, [Image], [Image], [Image], [Image], [Image] [Image]

Q: Name the angle in three different ways.

[Image]
- ∠ABC, ∠CBA, ∠B (You got it.)
- ∠ABC, ∠ACB, or ∠C (All three angle names must have the vertex letter in the middle.)
- ∠CAB, ∠CBA, or ∠A (Angle names must have the vertex letter in the middle.)
A: ∠ABC, ∠CBA, ∠B

Q: Use a protractor to measure the angle.

[Image]
- 180° (incorrect)
