Question

Determine if segment FT is tangent to circle P

Answer 1

• No, the segment is not tangent

-------------------------

Tangent line to a circle is perpendicular to a radius at the point of tangency. It makes the radius and tangent segments the legs of a right triangle.

To verify if the segment is tangent, use Pythagorean theorem:

• 25² = 9² + 19²
• 625 = 81 + 361
• 625 ≠ 442

This is false, hence the answer is no.
