WebStep 1: Spot the isosceles triangle. Segments \overline {\redD {BC}} B C and \overline {\redD {BD}} B D are both radii, so they have the same length. This means that \triangle CBD C B D is isosceles, which also means that its base angles are congruent: m\angle C = m\angle D = \blueD \psi m∠C = m∠D = ψ Step 2: Spot the straight angle.
