Draw each angle using a protractor: 140°, 65°, 50°, and 110°.

To draw these angles, you will need a protractor and a pencil. Here is the step-by-step method for each one:

General Steps for Drawing Any Angle:
1. Draw a straight horizontal line (this is your base ray). The dot in the image is where the two lines will meet (the vertex).
2. Place the center hole or crosshair of your protractor exactly on that dot.
3. Line up the "0°" mark on the protractor with your horizontal line.
4. Find the number for the angle you need on the curved edge of the protractor and make a small mark with your pencil.
5. Remove the protractor and use a ruler to draw a straight line from the dot to your new mark.

Here is how to do each specific problem:

1) 140°
* This is an obtuse angle (wider than a corner/L-shape).
* Place the protractor on the dot. Make sure you are reading the scale that starts at 0° on the right side.
* Count past 90° until you find 140°.
* Make a mark there and draw a line from the dot to the mark. The line should point up and to the left.

2) 65°
* This is an acute angle (smaller than a corner/L-shape).
* Place the protractor on the dot.
* Find 65° on the scale (it is between 60° and 70°).
* Make a mark and draw a line from the dot to the mark. The line should point up and to the right.

3) 50°
* This is also an acute angle.
* Place the protractor on the dot.
* Find 50° on the scale.
* Make a mark and draw a line from the dot to the mark. This line will be lower than the 65° line, pointing more to the right.

4) 110°
* This is an obtuse angle.
* Place the protractor on the dot.
* Find 110° on the scale (it is between 90° and 120°).
* Make a mark and draw a line from the dot to the mark. The line should point up and to the left, but not as far over as the 140° line.

Final Answer:
To complete the assignment, use a protractor to draw rays starting from the given points at the following measurements relative to the horizontal base line:
1. A ray at 140° (pointing up-left).
2. A ray at 65° (pointing up-right).
3. A ray at 50° (pointing up-right, lower than #2).
4. A ray at 110° (pointing up-left).
