Geometry Quiz 1
| Term | Definition |
|---|---|
| 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. |
