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 |
