When three points all lie on the same line, they are called ----? Collinear
a portion of a line that has both a starting and ending point A Segment
two rays that share the same starting point, called the vertex An angle
an angle that has a measure less than 90 degrees is called----- an acute angle
an angle that has a measure between 90 & 180 degrees is called--- an obtuse angle
an angle that has a measures exactly 90 degrees is called------ a right angle
an angle that has a measure of exactly 180 degrees is called---- a straight angle
two non-overlapping angels that share a ray are called----- adjacent angles
pairs of angles that share a vertex point and have rays that point in opposite directions are called----- vertical angles
two angles that have a sum of 90 degrees complementary angles
two angles that have a sum of 180 degrees supplementary angles
two lines, segments, or rays that form right angles with one another. Perpendicular
when a geometric object is cut into two of the same types of objects that have the same measure, it is called ---- A bisector, angle bisector or segment bisector
same size and same shaped figures congruent figures
same shape, different size, side lengths are porportional similar figures
Congruent Angles located in the same relative position on the two parallel lines are known as ------------------ corresponding angles
Congruent Angles located outside the parallel lines, & alternate side of the transversal are called----------- alternate exterior angles
