Corresponding Angles

Congruent angles found when a transversal intersects two parallel lines


bisect

to devide a geometric shape into 2 concruent parts.


side

1 ray of an angle.


transversal

A LINE THAT INTRSECTS 2 PARALLEL LINES.


VERTICAL ANGLES

OPPOITE CONGRUENT ANGLES FORMED BY INTRESECTING LINES.


perpendicular lines

lines that intersect to formright angles.


congruent

two geometric shapes having the same size and shapes.


plane

a flat surface.


Alternate interior angles

congruent angles formed by a transversal and parallel lines  on opposite sides of the transversal and outside the parallel lines.


right angle

an angle that measures exactly 90 degrees.


Alternate exterior angles

congruent angles formed by a transversal and parallel lines  on opposite sides of the transversal and outside the parallel lines


straight angle

an angle that measures exactly 180 degrees.


vertex

end point of an angle.


line

an infinite string of points.


collinear

on the same line.


reflex angle

angle that measures more then 180 degrees.


obtuse angle

measures more than 90 but less then 180 degrees.


angle

formed from 2 rays having the same end points.


ray

a line with one end point.


geometry

the study of the relaion ships of diffrent sets of points.


acute angle

an angle less than 90 degrees.
