## Geometric FiguresPresentation Transcript

• Geometric Figures Brice McDaniel Block 2
• Point
• Something that has position but not extension, as the intersection of two lines.
• Line (Segment)
• A part cut off from a figure, esp. a circular or spherical one, by a line or plane, as a part of a circular area contained by an arc and its chord or by two parallel lines or planes.
• Plane
• A surface generated by a straight line moving at a constant velocity with respect to a fixed point .
• Angle
• The space within two lines or three or more planes diverging from a common point, or within two planes diverging from a common line.
• Perpendicular Lines
• Lines that intersect and meet at a 90 degree right angle .
• Parallel Lines
• Lines that extend forever and never cross each other.
• Triangle
• A closed plane figure having three sides and three angles.
• Right Triangle
• A triangle containing a right angle.
• Pentagon
• A polygon having five angles and five sides.
• Hexagon
• A polygon having six angles and six sides.
• Square
• A rectangle having all four sides of equal length.
• Rectangle
• A parallelogram having four right angles.
• Trapezoid
• A quadrilateral plane figure having two parallel and two nonparallel sides.
• Parallelogram
• A figure that has four sides so that the two opposite sides are parallel and the other two sides are parallel to each other.
• Circle
• A closed plane curve consisting of all points at a given distance from a point within it called the center.
• Cylinder
• A surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.
• Sphere
• A solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center .
• Octagon
• A polygon having eight angles and eight sides.
• Triangular Prism
• A prism whose bases are triangles.
• Rectangular Pyramid
• A pyramid whose bases are all rectangles.
