## Geometry In The Real World ProjectPresentation Transcript

• Geometry in theReal World Project!!Theme: The Outdoors
Brittany Fielding
Block 05
• Point
Has no length or width, it just specifies a exact location.
• Line (Segment)
Line that does not extend forever, but has two distinct end points.
• Plane
A surface generated be 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
Two intersecting lines that form right angles
Slope is -1
• Parallel Lines
Lines that are always the same distance apart and will never meet.
• Triangle
A polygon with three vertices and three edges.
• Right Triangle
A triangle with one right angle
• Pentagon
Polygon with five sides
• Hexagon
A polygon with six sides
• Square
A rectangle having all four sides of equal length.
• Rectangle
A parallelogram with four right angles.
• Trapezoid
A quadrilateral plane figure having two parallel and two non parallel sides.
• Parallelogram
A quadrilateral having both pairs of opposite sides 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 form the center.
• Ray
Also called half-line
Originates at a point and extends in one direction from that point.
• Cone
A solid whose surface is generated by a line passing through a fixed point and a fixed plane curve not containing the point, consisting of two equal sections joined at a vertex.
• Acute Triangle
A triangle whose interior angles are all acute.
