Honors Geometry Chapter 1 Lesson 6

two dimensional figure

a set of continuous points

a curve that does not intersect itself

a curve that begins and ends at the same point

The set of all points in a plane and are a given distance from a given point

the center of the circle

any segment from the center to the edge

the union of a simple curve and its interior

a set is concave if a segment can be drawn whose endpoints are in the set but the segment is not completely contained in the set

a set is convex if every segment with end points in the set completely contained in the set

simple closed curves only consisting of segments (segment is a side, endpoints are vertexes)

having all sides equal in length

having equal angles

both equilateral and equiangular

three sides

four sides

five sides

six sides

seven sides

eight sides

nine sides

ten sides

eleven sides

twelve sides

n-gon (any number after twelve)

segments that go from one vertex to another nonconsecutive vertex

sum of all sides (distance around the figure)

p=ns

Radius x 2

any segment in a circle whose endpoints are on the circle (doesn't have to include the center)

a chord that contains the circle's center

a curve that is a subset of the circle

distance around a circle
