Vocabulary practice from chapter 1/geometry

AB
coordinate planeA number plane formed by two perpendicular number lines that intersect a their zero points
x-axisThe horizontal number line in a coordinate plane
y-axisThe vertical number line in a coordinate plane
originThe intersection of the x-axis and the y-axis and the coordinates are (0,0)
quadrantsThe four regions into which the x and y axes separate a plane
x-coordinateThe first component x, in an ordered pair
y-coordinateThe second component y, in an ordered pair
ordered pairUsed to locate points in a coordinate plane and are written in the form (x,y)
pointA basic undefined term in geometry that has no dimension and is represented by a dot
lineA basic undefined term in geometry that extends indefinitely in opposite directions, has no thickness and is represented by a line with arrows at each end
planeA basic undefined term in geometry that extends in all directions, has no thickness and is represented by a flat surface
collinear pointsPoints that lie on the same line
coplanar pointsPoints that lie on the same plane
midpointA point on a segment that separates the segment into two equal segments
segment bisectorA segment, line, or plane that separates a segment into two equal segments and
congruent segmentsSegments that are equal in measure
rayA straight set of points that begins with one endpoint and extends indefinitely in one direction
opposite raysTwo rays that have a common endpoint and extend in opposite directions
angleTwo noncollinear rays with a common endpoint
congruent anglesAngles that are equal in measure
angle bisectorA ray that separates an angle into two equal angles
protractorAn instrument used to measure angles
acute angleAn angle whose measure is less than 90 degrees
right angleAn angle whose measure is 90 degrees
obtuse angleAn angle whose measure is greater than 90 degrees and less than 180 degrees
straight angleAn angle who measure is 180 degrees
adjacent anglesTwo coplanar angles that have the same endpoint, a common side, and no interior points in common
vertical anglesA pair of angles formed by two intersecting lines such that the sides of one angle are opposite ray of the sides of the other angle
complementary anglesTwo angles whose sum is 90 degrees
supplementary anglesTwo angles whose sum is 180 degrees
linear pair of anglesTwo adjacent angles whose sum is 180 degrees
