• Points

• Line segment and Line

• Intersecting Lines

• Parallel line

• Ray

• Curve

• Polygon

POINT

• An exact location

• It has no size, only position

LINE SEGMENT & LINE

• A line segment is a part of line that is bounded by two distinct end point

• A line can be defined as a straight one-dimensional figure that has no thickness and extends endlessly in both directions

INTERSECTING LINES

• If two lines have one common point

PARALLEL LINES

• Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. 

RAY

• A portion of a line which starts at a point and goes off in a particular direction to infinity

CURVE

• Simple curve

• Open curve

• Closed curve

• Simple closed curve

POLYGON

• A simple closed

  figure made up of only line segments

• The lines segments forming a polygon are called its sides.

• The meeting point of a pair of sides is called its vertex.

• Any two sides with a common endpoint - Adjacent Sides
