Points, Lines, Planes

• Point- has no dimension. It usually is
  represented by a small dot. In this case it is
  used for mapping.
• Line-extends in one dimension. Represented by a
  straight line with two arrowheads to indicate
  that the line extends with out end in two
  directions. In this case its used for Power
  lines.
• Plane-extends in two dimensions. It usually is
  represented by a shape that looks like a tabletop
  or wall, it extends with out end. In this case
  the plane is the roof top.

Points, Lines, Planes cont

• Segment- a segment is a line with two end points
  in this case is a
• Intersecting lines- two lines that cross through
  each other In this case it is used as two
  crossing roads.
• Perpendicular lines- two lines that intersect
  creating a right angle. In this case it is used
  for a wrench.

• Angle- two different rays with the same initial
  point
• Acute Angle- an angle with the measure less than
  90Obtuse
• Angle- an angle with the measure more than 90

Polygons

• Triangle- a figure formed by three segments
  joining three non-collinear points, called
  vertices.
• Rectangle-a parallelogram with four right angles
• Right Triangle- a triangle with one right angle
• Square- a parallelogram with four congruent sides
  and four right angles

Circles

• Circle-The set of all points in a plain that are
  equidistant from a given point
• Diameter-A chord that passes through the center
  of the circle.
• Tangent line-a line that intersects a circle in
  exactly one point.

Solid Terms

• Pyramid-a polyhedron in which the base is a
  polygon and the lateral faces are triangles with
  a common vertex.
• Cylinder-a solid with congruent circular bases
  that lie in in a parallel planes.
• Sphere- The locus of points in space that are a
  given distance from a point called the center of
  the sphere.
