Your two pencils (rays) are lying down flat or straight on the floor. see it, you know that the measure of the angle is 90. For example, an angle with a vertex C, and a point A on the top ray, and the point B on the bottom … 161° b. In geometry, there are various types of angles, based on measurement. Example 4: Use Figure 13 to identify each named angle as acute, right, obtuse, or straight: (a) ∠ BFD, (b) ∠ AFE, (c) ∠ BFC, (d) ∠ DFA. It is an obtuse angle because its measure is greater than 90° but less than 180°.
