Midterm math study guide Flashcards
a two-dimensional pattern that you can fold to form a three dimensional figure
net
you can see the top, front, and side of an object in the same drawing
isometric drawing
shows the top view, front view, and right-side view of a three dimensional figure
orthographic drawing
indicates a location and has no size
point
a straight path that extends in two opposite directions without end and has no thickness. Infinitely many points
line
a flat surface that extends without end and has no thickness. It has infinitely many lines
plane
the part of a line that consists of two points, called endpoints, and all points between them
segment
part of a line that consists of one endpoint and all the points of the line on one side of the endpoint
ray
the set of points two or more geometric figures have in common
intersection
the distance and direction of a point from the origin of a number line
coordinate
the absolute value of the difference of the coordinates of the points
distance
the point that divides a segment into two congruent segments
midpoint
a line, segment, or ray that intersects a segment at its midpoint
segment bisector
two rays that have the same endpoint
angle
the endpoint of the two rays that form an angle
Vertex
angles that measures below 90
acute
angle that measures 90
right angle
angle that measures above 90
obtuse
angle that measures 180
straight
equal
congruent
two coplanar angles that have a common side and vertex but no common interior points
adjacent angles
two angles whose sides form two pairs of opposite rays
vertical angles
the sum of two angles equal 90
complementary angle
the sum of two angles equal 180
supplementary
a ray that divides an angle into two congruent angles
angle bisector
