Geometry Quiz 1

Acute Triangle A triangle for which all interior angles are acute, or less than 90 degrees.
Alternate exterior angles Exterior angles on alternate sides of the transversal.
Alternate interior angles Interior angles on alternate sides of the transversal.
Altitude of the polygon A straight line through a vertex and perpendicular to a line containing the base of a triangle
Angle bisector theorem Concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relatives lengths to the relative lengths of the other two sides of the triangle.
Angle bisector theorem, Converse If a point is equidistant from the sides of an angle, then it is on the angle bisector.
Angle Formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Arc A closed segment of a differentiable curve in the 2D plane.
Area Ant particular extent of space or surface.
Bisector A line that divides something into 2 equal parts.
Center of a polygon In a rotation, the point that does not move. The rest of the plane rotates around this one fixed point.
Centroid of a triangle The point where the three medians of the triangle intersect.
Circumcenter of a triangle The point where three perpendicular bisectors of a triangle meet.
Circumference A complete circular arc; also the distance around the outside of a circle.
Circumscribed A geometric figure that is drawn around another geometric figure so as to touch all its vertices.
Combination A way of selecting several things out of a larger group, where order does not matter.
Common parts Informal language that describes similarities, difference, parts and other attributes of two and three dimensional shapes, in different sizes and orientations.
Compass An instrument for drawing circles and arcs and measuring distances between points, consisting of two arms linked by a movable joint.
Complement probability In probability theory, the complement of any event A is the event i.e. the event that A does nor occur.
Complementary angle Two angles that add up to 90 degrees
Composition The combining of distinct parts or elements to form a whole
Compound event An event whose probability of occurrence depends upon the probability of occurrence of 2 or more independent events.
Compression To reduce a shape in size while retaining proportions.
Conditional probability The probability that an event will occur, when another event is known to occur or to have occurred.
Conditional probability formula The conditional probability of A given B is denoted by P(A|B) and defined by the formula P(A|B)=P(AB) P(B), Provided P(B)>0
Concurrency by AAS, ASA, SAS, SSS Triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.
Congruent Identical in form; coinciding exactly when superimposed.
Construction The drawing of various shapes using only a compass and straightedge or ruler. No measurement of lengths or angles is allowed.
Coordinates On the coordinate plane, the pair of numbers giving the location of a point. In three-dimensional coordinates, the triple of numbers giving the location of a point. In n-dimensional space, a sequence of n numbers written in parentheses.
