Define the word GEOMETRY The study of space (distance).Geometry is a branch of mathematics which involves the measuring of shapes. The word Geometry actually means "to measure the earth." What is this called? Line SegmentA LINE SEGMENT is represented by a group of points having tow endpoints. LINE SEGMENTS of the same length are congruent. What is this called? LineA LINE is represented by a group of points having no endpoints.  A line extends indefinitely in two opposite directions. What is this called? RayA RAY is represented by a group of points having one endpoint. A RAY extends indefinitely in one direction. What is this called? AngleAn ANGLE is two rays that share a common endpoint.  The common endpoint is called the vertex. What is this called? Intersecting LinesINTERSECTING LINES are lines that cross each other at some point. What are these lines called? Perpendicular LinesPERPENDICULAR LINES are intersecting lines that form four right angles. What is a PLANE? A PLANE is represented by a smooth, flat surface that has no thickness and extends indefinitely in all directions. What are these lines called? Parallel LinesPARALLEL LINES are lines that never intersect. What are these shapes? Simple Closed FiguresSIMPLE CLOSED FIGURES do not have a point of intersection. What are these shapes? Similar FiguresSIMILAR FIGURES have the same shape but not the same size. What are these shapes? Congruent FiguresCONGRUENT FIGURES have the same size and shape. What are these shapes? PolygonsA POLYGON is a simple closed figure made up of line segments. what is this shape? TriangleA TRIANGLE is a polygon with 3 sides. What is this shape? QuadrilateralA QUADRILATERAL is a polygon with 4 sides. What is this shape? ParallelogramA PARALLELOGRAM is a quadrilateral having opposite sides which are parallel. What is this shape? RectangleA RECTANGLE is a parallelogram having 4 right angles. The box in the corner means perpendicular lines forming a right angle. What is this shape? SquareA SQUARE is a rectangle having 4 congruent sides.  The double line segments on each side means they are congruent. What is this shape? RhombusA RHOMBUS is a parallelogram having 4 congruent sides. What is this shape? TrapezoidA TRAPEZOID is a quadrilateral having only 2 sides that are parallel. What is this shape? PentagonA PENTAGON is a polygon having 5 sides. What is this shape? HexagonA HEXAGON is a polygon having 6 sides. What is this shape? OctagonA OCTAGON is a polygon having 8 sides. What is this shape? HeptagonA HEPTAGON is a polygon having 7 sides. What are the points called where the sides of the polygon meet?  (point A, B, C or D) Vertexes What is the line called that joins two opposite vertexes (line BD)? DiagonalA DIAGONAL is not a side.
