set of points in a plane that are a fixed distance from a given point called the center of the circle circle
distance around a circle circumference
circles that have congruent radiicongruent circles
set of all points inside a circleinterior of a circle
the ratio of the circumference of a circle to its diameter, denoted by the greek letter (pie)Pi
segment whose endpoints are the center circle and a point on the circle; also the length of a circleradius of a circle
argument that uses logic to show that a conclusion is trueproof

Section 2

Question Answer
triangles whose corresponding sides and angles are congruentcongruent triangles
angles in the same relative position in two different polygons with the same number of anglescorresponding angles of polygons
sides in the same relative position in two different polygons with the same number of sidescorresponding sides of polygons
"corresponding parts of congruent triangles are congruent"- can be justified in a proof after two triangles are proven congruentCPCTC
property of triangles that states that if the side lengths of a triangle are fixed, the triangle can have only one size and shapetriangle rigidly

angle whose vertex is the center of a circlecentral angle of a circle
areas that are in the same or congruent circles and have the same measurecongruent arcs
arc of a circle whose points are on or in the exterior of a central anglemajor arc
difference of 360 degrees and the measure of the associated minor arcmeasure of a major arc
measure of its central angle measure of a minor arc
