That last category, the elite members, always includes the regular polygon. Obviously, as the number of sides increases, the sizes of the two circles become closer and closer. GMAT questions about inscribed and circumscribed polygons are rare, and may test both your understanding of terminology and your visualization skills by describing the geometric situation e. This is one special case the GMAT loves.
This is a powerful set of ideas because the deductions run both ways and because it inextricably connects two seemingly disparate ideas. Ready to get an awesome GMAT score? Start here.

Inscribed Quadrilaterals and Triangles A quadrilateral can be inscribed in a circle if and only if its opposite angles are supplementary.
If a right triangle is inscribed in a circle, then the hypotenuse is a diameter of the circle. Conversely, if one side of an inscribed triangle is a diameter, then the triangle is a right triangle, and the angle opposite the diameter is a right angle. Example: For each inscribed quadrilaterals find the value of each variable. Cyclic Quadrilaterals In this lesson we looked at properties of cyclic quadrilaterals. A cyclic quadrilateral is a four sided figure whose corners are on the edge of a circle.
Inscribed Triangles If an inscribed triangle is a right triangle, then the hypotenuse is the diameter. If an inscribed angle has a diameter as one of its sides, then its a right triangle. Circles Inscribed in Right Triangles This problem involves two circles that are inscribed in a right triangle. Example: The circle with center A has radius 3 and its tangent to both the positive x-axis and the positive y-axis.
The circle with center B has radius 1 and is tangent to both the x-axis and the circle with center A.
