a) Prove that CAD is isosceles. Step 1: Identify parallel lines and transversal angles. Given that AD || CG. Considering AC as a transversal, we have DAC = ACG (alternate interior angles). Step 2: Use the given angle equality. We are given that C_2 = C_3, which means ACG = BCG. Step 3: Combine the angle equalities. From Step 1 and Step 2, we have DAC = BCG. Step 4: Use angles subtended by the same arc. Angles subtended by the same arc at the circumference are equal. BAG and BCG are both subtended by
