2. Measuring Segments and Creating Midpoints
a. Measure the length of segment AB. Select the Distance or Length tool . Then, select point followed by point B. Alternatively, you can simply select the Distance or Length tool and click on the line segment. Select the move tool and drag points A and or B. Note how the measurement between those two points changes in real time.
b. Plot a midpoint on line segment CD. Select the Midpoint or Center tool , and select points C and D. Using the Distance or Length tool , measure the distance between C and the midpoint (should be point E) , and then measure the distance between D and the midpoint.
. Then, select point followed by point B. Alternatively, you can simply select the Distance or Length tool and click on the line segment. Select the move tool and drag points A and or B. Note how the measurement between those two points changes in real time.
b. Plot a midpoint on line segment CD. Select the Midpoint or Center tool , and select points C and D. Using the Distance or Length tool , measure the distance between C and the midpoint (should be point E) , and then measure the distance between D and the midpoint. 3. Measuring angles
a. Measure angle ABC. Select the Angle tool . Select point A followed by point B followed by point C. Alternatively, select point C followed by point B followed by point A. Note how the angle is adjacent to vertex B, and B is always selected second because it is in between points A and C. Use the move tool to select the angle measure and move so it is easier to see.
b. Measure all angles formed by line segments QT and SU. Using your knowledge of your work from above, measure all angles in the diagram below using the Angle tool . Note how you will always select R second. As an example, measure angle QRS by selecting point Q followed by point R followed by point S (or S followed by R followed by Q).
. Select point A followed by point B followed by point C. Alternatively, select point C followed by point B followed by point A. Note how the angle is adjacent to vertex B, and B is always selected second because it is in between points A and C. Use the move tool to select the angle measure and move so it is easier to see.
b. Measure all angles formed by line segments QT and SU. Using your knowledge of your work from above, measure all angles in the diagram below using the Angle tool . Note how you will always select R second. As an example, measure angle QRS by selecting point Q followed by point R followed by point S (or S followed by R followed by Q).
