Question

In the figure provided, ⊙A is given with a radius of 3, BC=4, and CB←→ tangent to ⊙A at B. Can it be concluded that AC=5? Explain.

  • No, AC does not necessarily equal 5. Although the triangle is a right triangle, AC can be a range of values.

  • No, AC does not necessarily equal 5. It cannot be determined that ∠ABC is right.

  • Yes, AC=5. Since AB=3 and BC=4, the triangle must be right, and so the remaining side length must be 5.

  • Yes, AC=5. Since ∠ABC is right, the triangle is right, and so the remaining side length must be 5.
