geometry 1.1 points, lines, planes

Intersecting lines are ____________ coplanar. always sometimes never Three points are ____________ collinear. always sometimes never Name the red line. A B W C D D AW CB Which of the following is NOT a ray shown in the drawing? AC A BCA B CBA C CA Which of the following set of points ARE coplanar? AHBC DCBE AHCD EDCA A E H B D C A E G B F C D DCG EGA AFD EFD Name a plane that is parallel to plane ABC. Do all segments have a midpoint? false true A __________ has two endpoints. line ray segment angle W S Z V X T Y U Which point is contained in plane TUY? W V Z X A location in space is the definition of a . . . line plane point ray Two points __________ create a line. never maybe always sometimes Match the following definitions. Put the correct letter in the box. Obtuse Angle Parallel lines Point Skew Use lower case letters. b. An angle between 90 and 180 degrees a. location in space c. noncoplanar lines that do not intersect. d. coplanar lines that do not intersect Match the following definitions. Put the correct letter in the box. Collinear points Parallel planes Intersect Plane Coplanar e. lie in the same plane d. planes that do not intersect b. flat surface that extends in all directions a. share at least one point c. points that lie on the same line Use lower case letters. Match the following definitions. Put the correct letter in the box. Ray Segment Space c. the set of all points a. part of a line with 2 endpoints b. part of a line with one endpoint Use lower case letters. M N O P Are O, N, and P collinear? If so, name the line on which they lie. Yes, they lie on the line MP. Yes, they lie on the line NP. Yes, they lie on the line MO. No, the three points are not collinear. Name the ray that is opposite BA. A B C D BD BA DA CA segment point line sometimes a point, sometimes a line Two planes intersect at a ____________. How many points are needed to create a unique plane? MYou can always find the midpoint of a line. True False Sometimes true, sometimes false Collinear means ____________. there are lines that coexist in the same plane. the points are near each other. trick question - collinear is not a real word the points are on the same line |
