Vocab Flashcards
math
the point where 2 sides intersect
vertex
no beginning or end point continues to infinity
line
2 points connected with a straight line
line segment
starts at one point and continues to infinity
ray
a flat surface that extends infinitely in all directions
plane
same size, same shape
congruent
formed by 2 rays with a common endpoint
angle
lines in a plane that do not intersect
parallel lines
lines that intersect to form a right angle
perpendicular lines
same position on the parallel lines in relation to the transversal always congruent
corresponding angle
inside the parallel lines and on opposite sides of transversal always congruent
alternate interior angles
outside the parallel lines and on opposite sides on the transversal always congruent
alternate exterior angles
same side of transversal and inside the parallel lines always supplementary
consecutive interior angles
supplementary
180 degree
complementary
90 degree
two angles that share a common vertex and a side
adjacent angle
opposite angles formed by intersecting lines
vertical angle
less than 90 degree
acute
exactly 90 degree
right
greater than 90 degree and less than 180 degree
obtuse
exactly 180
straight
