| Question | Answer |
|---|---|
| has no size; only location | point |
| a flat surface that extends in 4 directions (window) | plane |
| continues w/ out end in opposite directions | line |
| part of a line w 2 endpoints | lins segmelt |
| part of a line w/ 1 endpoint | ray |
| lines in the same plane thAT never intersect | parallel lines |
| lines that intersect to form 2 right angles | perpendicular lines |
| lines that lie in diff. planes , neither parallel or perpendicular | skew lines |
| the sum of the angles = 90degrees | complimentary angles |
| the sum of the angles=180degrees | supplimentary angles |
| 2 angles that share a common vertex & a common ray | adjacent angles |
| 2 angles that are formed by intersecting lines & they only have a common vertex & congruent | vertical angles |
| a closed shape formed by line segments that do not intersect | polygon |
| segment that connects 2 verticies but is not an edge | diagonal |
| all sides congruent(triangle) | equalateral |
| 2 sides congruent ( triangl) | isosceles |
| no congruent sides (triangle) | scalene |
| 1 right angle & acute angles | right |
| 3 acute angles... (triangle) | acute |
| 1 obtuse angle (triangle) | obtuse |
| quadrilateral w 2 pairs of parallel lines | parallelogram |
| a parallelogram w 4 right angles | rectanle |
| a parallelogram w 4 congruent &4 right angles | square |
| parallelogram w 4 congruent sides | rhombus |
| a quad. w only 1 pair of parallel lines | trapezoid |
| line seg. w independent at the circle & the other on the circle | radius |
| line seg. w both endpoints on the circle& goes thru the center of circle | diameter |
| line seg. w both endpoints on the corcle | chord |
| vertex is in the center of the circle of the circle & rays on the end of the circle | central angle |
| part of circle; less than half | arc |
| exactly 1/2 of the circle | semi-circle |
