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 |
