    You will need the following equipment for these lab activities:

    360-degree and 180-degree protractors.
    Figure 1.12: Protractor examples. A 360-degree protractor example is on the left, and a classic 180-degree protractor on the right. Both are commonly used for scientific purposes.

    1. Using your protractor, measure the angle of the arrow below.

    Figure 1.13.1, an acute angle for measurement.
    Figure 1.13.1: An acute angle for measurement.

    2. Using your protractor, measure the angle of the arrow below.

    Figure 1.13.2, an acute angle for measurement.
    Figure 1.13.2: An acute angle for measurement.

    3. Using your protractor, measure the angle of the arrow below.

    Figure 1.13.3, an acute angle for measurement.
    Figure 1.13.3: An acute angle for measurement.

    4. Using your protractor, measure the angle of the arrow below.

    Figure 1.13.4, an obtuse angle for measurement.

    5. Below is a compass rose, which indicates the cardinal directions. North (N) is always represented as 0°/360°. On the compass below, label:

    a. The remaining cardinal directions (S, W, E) in black.

    b. The intermediate points (NE, SE, NW, SW) in brown.

    c. The intermediate points of the intermediate points (NNE, ENE, ESE, SSE, SSW, WSW, NNW, WNW) in blue.
