verify a tangent to a circle
{"Image DocumentName": "Verify a tangent to a circle", "Image ImageDescription": "EXAMPLE In the diagram, PT is a radius of \u0298 P. Is ST tangent to \u0298 P ? SOLUTION. Use the Converse of the Pythagorean Theorem. Because = 372, \u25b3 PST is a right triangle and ST \uf05e PT . So, ST is perpendicular to a radius of \u0298 P at its endpoint on \u0298 P. ST is tangent to \u0298 P.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
