Step 1: First, draw a ray OB and align the protractor with OB as shown. ... 24° lies in between 0° and 90°, so it is an acute angle. (b) 154° lies in between 90° and 180°, so it is an obtuse angle. (c) 90° is known as the right angle. ...
WebMar 1, 2024 · This means that C O ― is the angle bisector of the angle ∠ A C B. The same line segment divides the opposite side, A B ―, into two line segments. The angle bisector theorem states that when this happens, the affected line segments and the two sides of the triangle are proportional. A C A O = B C B O 24 18 = 16 12 4 3 = 4 3.

WebSep 15, 2024 · We know that ABC is a right triangle. So as we see from Figure 2.5.3, sinA = 3 / 5. Thus, 2R = a sinA = 3 3 5 = 5 ⇒ R = 2.5 . Note that since R = 2.5, the diameter of the circle is 5, which is the same as AB. Thus, ¯ AB must be a diameter of the circle, and so the center O of the circle is the midpoint of ¯ AB.
