Answer

$\triangle AOC$ is an equilateral triangle

Here are the solutions to the questions.

4.1 Show that $\hat{C}_2 = \hat{D}_1$ .

Step 1: Use the given information that $AC = AO$ and O is the center. Since O is the center, $OA = OC$ (radii). Given $AC = AO$ , it follows that $AC = AO = OC$ . Therefore, $\triangle AOC$ is an equilateral triangle. This means all its angles are $60^\circ$ . $\angle OAC = \angle OCA = \angle AOC = 60^\circ$ From the diagram, $\hat{C}_1 = \angle OCA$ , so $\hat{C}_1 = 60^\circ$ .
