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 |
