B 23. What type of angle is CMK? A. right angle B. acute angle C. obtuse angle Open Response (2 points each) 24. Identify the number of each type of angle in figure 1: 2 right angles 1 acute angles Figure 1 2 obtuse angles
Now compare the angles in Figure 1 to the angles in Figure 2.
Figure 1 has three different types
of angles, while figure 2 only has
right angles. Figure 1 only has 2
right angles, but figure 2 has 4. Figure 2
25. For each figure below, highlight one pair of perpendicular line segments. (There may be shapes that do not have any).
Explain how to identify perpendicular lines.
To find perpendicular lines, look for two lines
or line segments that form a right angle.
