    Geometry Review help

    Hi there,

    Please review/help me fill in my guide to make sure it's right.

    Geometry

    point - a location in space

    line - a collection of points

    infinite - never ending

    plane - a collection of lines (flat surface)

    space - the collection of all planes

    collinear - points in the same line

    non-collinear - points not on the same line

    co planar - points or lines on the same planes

    non co-planar - points or lines not on the same plane

    intersect - cross (meet at a point)

    -------------------------------------------------------------------------

    Distance

    Distance - Length of a segment. Distance formula -

    d= x2-x1 (2) + y2-y1 (2)

    Midpoint

    Midpoint - Point in the middle. Midpoint formula -

    m = a+b
    ----
    2


    more vocab

    ray - piece of a line w/ one end point

    angle - the union of two rays at one end point

    angles measure in degrees

    acute angles are smaller than 90 degrees

    right angles are 90 degrees

    straight angles are 180 degrees

    obtuse angles are bigger than 180 degrees

    -------------------------------------------------------------------------

    here's where I am starting to have some troubles.

    Please help if you can.

    bi sector - cuts a segment or angle in half.

    adjacent angels - have a common side and a common vertex (side by side) no common interior points.

    vertical angles - common vertex, no common ?

    linear pair - have a common vertex and form a straight line.

    complementary angles

    2 c's that add up too 90 degrees . ex: 15 degrees and 75 degrees.


    supplementary angles - 2 c's that add up to 180 degrees. ex 10 degrees and 170 degrees

    perpendicular lines - intersecting lines that form a right L


    OK, Here's where I need help please

    The math portion



    I don't understand this, please help

    Thanks
