Circle DefinitionsDate: 04/29/2002 at 14:02:52 From: Katie Troutman Subject: Circles Define a circle and its parts: diameter, radius, center, circumference. Date: 04/29/2002 at 14:17:40 From: Doctor Sarah Subject: Re: Circles Hi Katie - thanks for writing to Dr. Math. The center of a circle is the same distance from all points on the circle and is the intersection of any two different diameters. From the Harcourt Multimedia Math Glossary: http://www.harcourtschool.com/glossary/math_advantage/glossary5.html A circle is a closed figure with all points on the figure the same distance from the center point. The diameter is a line segment that passes through the center of a circle and has its endpoints on the circle. The radius is a line segment with one endpoint at the center of a circle and the other endpoint on the circle. The circumference is the perimeter of a circle. A chord is a line segment with endpoints on a circle. - Doctor Sarah, The Math Forum http://mathforum.org/dr.math/ |
