product | | a unit of measure for angles based on dividing up a circle into 360 parts. A unit of measure for temperature. |

hundredth | | a letter or other symbol that represents a number example 5 + X = 9 and x=4 to make the number sentence true |

intersect | | a number that is written using both a whole number and a fraction |

right triangle | | the answer in multiplication |

acute angle | | one of two numbers that are multiplied to give a product |

obtuse angle | | a point at the end of a line segment or ray |

right angle | | a straight path joining 2 points. the two points are called "endpoints" (------------------- ) |

endpoint | | a figure measuring exactly 90* that is formed by two rays or two line segments with a common endpoint |

angles | | a straight path that extends infinitely in opposite directions |

lines | | a straight path that starts at one point (the endpoint) and continues forever in one direction |

mixed number | | a whole number that has exactly two factors: itself and 1 |

perpendicular | | the digit two spaces to the right of a decimal can be written as 1/100 or 0.01 |

ray | | common fractions that serve as benchmarks or points of reference to help us estimate other fractions. |

benchmark fractions | | a triangle that has a right angle (90*) |

common denominator | | a figure that is formed by two rays or two line segments with a common endpoint |

degree | | crossing or meeting at right angles. The symbol means is perpendicular to |

decimal notation | | a figure measuring less than 90* that is formed by two rays or two line segments with a common endpoint |

line segment | | a model that shows the amount of surface inside a closed boundary (such as a shape labeled in square units) |

line of symmetry | | a line drawn through a figure that creates two "mirror" images of eachother |

parallel | | a whole number with more than two factors |

variable | | a dot used to separate the ones and the tenths place in decimal numbers |

factor | | if two fractions have the same denominator |

prime number | | to meet or cross |

composite number | | a figure measuring more that 90* and less than 180* that is formed by two rays or two line segments with a common endpoint |

remainder | | an amount left over when one number is divided by another number |

area model | | ( ) lines, line segments, rays or ("planes) are said to be parallel if they never cross or meet, no matter how far they extend |
