This question requires knowledge of three different areas:
1. Basic properties of circles - What is a diameter and what is a radius?
2. Properties of circles - angle in a semicircle is 90 degrees
3. Concept of similar triangles
Additionally, reasoning skills are important for this question (because I need to show that angle CAK = angle BCK so that I can use this fact as one of the conditions/prerequisites for the proving of the similarity of the triangles).
