Collinear lines are on the same line.
Because, in this four sided figure, the opposite sides are parallel to each other.
A triangle.
The proposed name for a nine sided polygon is Nonagon or Enneagon. If you were going to talk about a 99 sided polygon then you would call it an Enneacontakaienneagon. Polygons are a plane figure where each line segment touch each other but do not cross each other.
A 12 sided figure is called a dodecagon. This type of polygon has 12 angles and each angle equals 150 degrees.
Parrallogram
A line.
Because, in this four sided figure, the opposite sides are parallel to each other.
If the figure has eight sides, but they are not equal, it has no special name. It would just be called an eight-sided polygon. A polygon is a closed figure made by joining line segments, where each line segment intersects exactly two others.
A diagonal.
Symetrical line
A triangle.
Motorcade, if the political figure is alive at the time. Otherwise it is a cortege.
No. Two lines perpendicular to the same line are parallel to each other. I am doing this for my geometry homework right now trying to recall the name of the postulate/theorem stating it.
figure
Center Court Line, Free Throw Line and Base Line.
A diagonal.A diagonal.A diagonal.A diagonal.
tottaly my name is Kristen and anyone who is willing to try to work things out on line is someone who is seriously smart in relationships. You to have got to be made for each other
