Question

Given: DC is a diameter of circle k (O). DC ⊥ AB Prove: AC ≅ BC

Answer 1

Answer:

See explanation

Step-by-step explanation:

Connect points A and O and B and O. Consider two right  triangles AOE and BOE. In this triangles,

• AO=BO as circle's radii;
• OE is common leg.

By HL theorem, these triangles are congruent, thus, AC=BC.
