Question
Answer
acute angle   an angle whose measure is between 0-90  
🗑
right angle   an angle whose measure is 90  
🗑
obtuse angle   an angle whose measure is 90-180  
🗑
parallel lines   two lines are parallel if they lie on the same plane and do not intersect  
🗑
skew lines   Skew or skew lines lie on different planes. They are neither parallel nor intersecting. Mathematics In geometry, straight lines in a space referred to as skew if they ...  
🗑
perpendicular lines   lines that intersect and form right angles.  
🗑
collinear points   points that lie on the same line  
🗑
coplanar   being or operating in the same plane  
🗑
opposite rays   are collinear rays with the same end point. They form a line.  
🗑
perpendicular bisector   The perpendicular bisector of a segment is a line, segment, or ray that is perpendicular to the segment at its midpoint.  
🗑
segment   part of a line consisting of two points called endpoints, and all points in between them.  
🗑
ray   part of a line consisting of one endpoint and all the points of the line on one side of the endpoint  
🗑
line   a series of points that extend in two directions  
🗑
midpoint   the point that divides a segment into two congruent segments  
🗑
midsegment   line in the center of a figure  
🗑
complementary angles   two angles that are complementary angles if the sum of their angles measures is 90  
🗑
supplemenary angles   two angles are supplementary if the sum of their measures is 180  
🗑
adjacent angles   two coplanar angles that have a common side and a common vertex but no common interior points.  
🗑
multiplication property of equality   if a=b, then a.c = b . c  
🗑
addition property of equality   if a = b than a + c = b + c  
🗑
subtraction property of equality   if a = b then a - c = b - c  
🗑
division property of equality   if a = b then c does not equal 0 then a/c + b/c  
🗑
