Measuring an Angle:

1. Align Vertex: Place the protractor's center point (often marked with a small cross or hole) directly over the vertex (corner) of the angle you wish to measure.
2. Align Base Line: Align the protractor's straight base line (0°/180° line) with one of the angle's rays.
3. קרא מדידה: Read the degree measurement where the second ray of the angle intersects the protractor's curved scale. Use the inner or outer scale depending on which side of the base line the angle opens.

Drawing an Angle:

1. Draw Base Ray: Use the protractor's ruler base to draw a straight line, which will serve as the first ray of your angle. Mark the vertex point on this line.
2. Align Protractor: Place the protractor's center point on the marked vertex, and align its base line with the drawn ray.
3. Mark Degree: Locate the desired degree measurement on the protractor's curved scale and make a small mark on your paper at that point.
4. Draw Second Ray: Remove the protractor. Use a straight edge (the protractor's ruler base can be used) to draw a line from the vertex through the mark you just made. This completes your angle.

Using the Ruler Base:

The straight edge of the protractor features a 6-inch ruler. This can be used for drawing straight lines or for making linear measurements in inches.
