Making Connections Glossary
height  
  (a) Triangle: the length of a segment that connects a vertex of the triangle to a line containing the opposite base (side) and is perpendicular to that line.  (b) Trapezoid: the length of any segment that connects a point on one base of the trapezoid to the line containing the opposite base and is perpendicular to that line.  (c) Parallelogram (includes rectangle, rhombus, and square): the length of any segment that connects a point on one base of the parallelogram to the line containing the opposite base and is perpendicular to that line.  (d) Pyramid and cone: the length of the segment that connects the apex to a point in the plane containing the base of a figure and is perpendicular to that plane.  (e) Prism or cylinder: the length of a segment that connects one base of the figure to the plane containing the other base and is perpendicular to that plane.  (See altitude.)
hexagon  
  A polygon with six sides.
histogram  
  A way of displaying data that is much like a bar graph in that the height of the bars is proportional to the number of elements.  The difference is that each bar of a histogram represents the number of data elements in a range of values, such as the number of people who weigh from 100 pounds up to, but not including, 120 pounds.  Each range of values should have the same width.  (See bar graph.)
   
horizontal  
  Parallel to the horizon.  The x-axis of a coordinate grid is the horizontal axis.
hypotenuse  
  The longest side of a right triangle (the side that is opposite of the right angle).  (See Pythagorean Theorem for a diagram.)
