| Question | Answer |
|---|---|
| the opening that is formed when two rays intersect | angle |
| lines in the same plane that aren't parallel or perpedicular | oblique lines |
| having the same size and shape | congruent |
| triangle whose angle is more than 90 degrees | obtuse |
| where two points meet | vertex |
| a line segment that is part of polygon | side |
| a triangle where all three sides of it have the same length | equilateral |
| where two lines share a point or points | intersect |
| triangle with three sides of different length | scalene |
| two ines that intersect at right angles | perpendicular |
| a flat surface that has no boundaries | plane |
| any four-sided polygon | quadrilateral |
| a triangle whose angle measures 90 degrees | right triangle |
| having the same shape but not necessarily having the same size | similar |
| to express a calculation or measure to a specific degree or accuracy | round |
| a closed flat shape with straight sides | polygon |
| any four-sided polygon | quadrilateral |
| lines that stay the same distance apart | parallel |
| difference between starting time and ending time | elapsed time |
| a number that has not been rounded | exact number |
| to share a point or points | intersect |
| lines that cross | intersecting lines |
| lines in the same plane that are neither parallel nor perpendicular | oblique lines |
| lines that stay in the same distance apart; lines that do not cross | parallel lines |
| two lines that intersect at right angles | perpendicular lines |
| an angle whose measure is more than 0 degress and less than 90 degrees | acute angle |
| the opening that is formed when two lines, line segments, or rays intersect | angle |
| having the same size and shape | congruent |
| an angle whose measure is more than 90 degrees and less than 180 degrees | obtuse angle |
| a flat surface that has no boundaries | plane |
| a closed, flat shape with straight sides | polygon |
| any four-sided polygon | quadrilateral |
| and angle that forms a square corner and measures 90 degrees; it is often marked with a small square | right angle |
| a line segment that is part of a polygon | side |
| having the same shape but not necessarily the same size; these kinds of figures are proportional | similar |
| an angle that measures 180 degress and thus forms a straight line | straight angle |
| a point of an angle, polygon, or solide where two or more lines or line segments meet | vertex |
| plural of "vertex" | vertices |
| a number that has not been rounded | exact |
| to express a calculation or measure to a specific degree or accuracy | round |
| a whole number that ends with one or more zeros | round number |
| the difference between the starting time and ending time | elapsed time |
| a triangle whose largest angle measures less than 90 degrees | acute triangle |
| a triangle in which all sides are the same length | equilateral triangle |
| a triangle with at least two sides of equal length | isosceles triangle |
| a triangle whose largest angle measures more than 90 degrees and less than 180 degrees | obtuse triangle |
| a triangle whose largest angle measures 90 degrees | right triangle |
| a triangle with three sides of different lengths | scalene triangle |
