an angle with a degree measure less than 90.
Blur Image
two angles that lie in the same plane, have a common vertex and a common side, but no common interior points.
Blur Image
the intersection of two noncollinear rays at a common endpoint. the rays are called sides and the common endpoint is called the vertex.
Blur Image
a ray that divides an angle into two congruent angles.
Blur Image
points that lie on the same line.
Blur Image
two angles with measures that have a sum of 90.
Blur Image
having the same measure.
Blur Image
points that lie on the same plane.
Blur Image
a unit of measure used in measuring angles and arcs. an arc of a circle with a measure of 1 degree and 1/360 of the entire circle.
Blur Image
the length of the segment between two points.
Blur Image
a basic undefined term of geometry. a line is made up of points and has no thickness or width. in a figure, a line is shown with an arrowhead at each end. lines are usually named by lowercase script letters or by writing capital letters for two points on the line, with a double arrow over the pair of letters.
Blur Image
a measurable part of a line that consists of two points, called endpoints, and all the points between them.
Blur Image
a pair of adjacent angles whose noncommon sides are opposite rays.
Blur Image
the point on a segment exactly halfway between the endpoints of a segment.
Blur Image
an angle with degree measure greater than 90 but less than 180.
Blur Image
two rays, ray BA and ray BC, such that B is between A and C.
Blur Image
lines that form right angles.
Blur Image
a basic undefined term of geometry. a plane is a flat surface made up of points that has no depth and extends indefinitely in all directions. in a figure, a plane is often represented by a shaded, slanted four-sided figure. planes are usually named by a capital script letter or by three noncollinear points on the plane.
Blur Image
a basic undefined term of geometry. a point is a location. in a figure, points are represented by a dot. points are named by capital letters.
Blur Image
ray PQ is a ray if it is the set of points consisting of line segment PQ and all points S for which Q is between P and S.
Blur Image
an angle with a degree measure of 90.
Blur Image
a segment, line, or plane that intersects a segment at its midpoint.
Blur Image
a boundless three-dimensional set of all points.
Blur Image
two angles with measures that have a sum of 180.
Blur Image
the common endpoint of an angle.
Blur Image
two nonadjacent angles formed by two intersecting lines.
