Question  Answer 

Transversal  A line that intersects two coplanar lines at two distinct points 
Segment  The part of a line consisting of two endpoints 
Coplanar  Points and lines that lie on the same plane 
Adjacent  Two coplanar angles with a common side, a common vertex, and no common points 
Midpoint  A point ona segment that divides a segment into two congruent segments 
Concave  A polygon with at least one diagonal that falls outside the polygon 
Complementary  Two angles whose measures have a sum of 90 degrees 
Obtuse  An angle whose measure is greater than 90 degrees 
Corresponding  Two angles that are in the same position on a transversal 
Straight  An angle whose measure is equal to 180 degrees 
Skew  Two or more noncoplanar lines 
Hypotenuse  The longest side of a right triangle 
Orthocenter  The point of concurrency of the altitudes of a triangle 
Parallel  Two or more coplanar lines that do not intersect 
Centroid  The point of concurrency of the medians of a triangle 
Altitude  The perpendicular segment from a vertex to the line containing the opposite side 
Supplementaty  Two angles whose measure have a sum of 180 degrees 
Median  A segment in a triangle whose endpoints are a vertex and the midpoint of the opposite side 
Acute  An angle whose measure is less than 90 degrees 
Concurrent  When three or more lines intersect at one point 
Circumcenter  The point of concurrency of the perpendicular bisectors of a triangle 
Vertical  Two angles whose sides form two pairs of opposite rays 
Convex  A polygon with no diagonals that lie outside the polygon 
Polygon  A closed plane figure with at least three sides that are segments, the sides only intersect at their endpoints 
Inverse  Negates both of the hypothesis and conclusion of a conditional 
Contrapositive  Switches the hypothesis and the conclusion and negates both of them 
Converse  Switches the hypothesis and conclusion in an "ifthen" statement 
Incentor  The point of concurrency of the angle bisectors of a triangle 
Conditional  Another name for an "ifthen" statement 
Midsegment  A segment in a triangle connecting the midpoints of two sides 
Regular  A polygon with all sides and angles the same 
Right  An angle whose measure is equal to 90 degrees 
CPCTC  Used to prove angles or sides of triangles are congruent
