Divides a line segment or angle into two equal parts
Having the exact same shape or size
Two lines in the same plane that are the same distance apart and will NEVER touch.
Two lines that intersect to form right angles
The part of a line that is between two points
The points st the end of a line segment
The point at which two or more lines intersect or cross
A line that starts at a point and goes on forever in one direction.
a plane is a flat surface with no thickness. Coordinate planes have lines on them
to draw geometric shapes and lines with a compass and a straight edge
reflection, translation, rotation and dilation are examples.
turning a figure around a fixed point
a lin eon a plane is like a mirror. A geometric figure is flipped over on the other side of the line
changes the size of a figure
common end point of two rays
formed by two rays with a vertex. The two rays are the sides of the angle
less than 90*
more than 90 but less than 180
lines that are not on the same plane and do not intersect but they aren't parallel
have a common vertex and a common side but no common interior points
the opposite angles formed by two intersecting lines.
a line that intersects 2 or more lines
On the same side of the transversal and are both above and below .
