## Geometric Objects PpPresentation Transcript

• GeometricObjects
By: Connor Zalesak
Block 5 P-AP Geometry
• Point
Names a location
Has no size
Represented by a dot
• Line
Straight path
Has no thickness
Extends forever
There is one between any two points
• Plane
Flat surface
Has no thickness
Extends forever
• Angle
A figure formed from two rays with a common endpoint
• PerpendicularLines
Intersect at a 90 degree angle
• Parallel Lines
Never intersect
Extend forever
• Triangle
Three sided polygon
180 degrees
• RightTriangle
Three sided polygon
180 degrees
The two “legs” make a right angle
• Pentagon
Five sided polygon
540 degrees
• Hexagon
Six sided polygon
720 degrees
• Square
Four sided polygon
360 degrees
Every side and angle is congruent
• Rectangle
Four sided polygon
360 degrees
The sides parallel to each other are the same length
All angles are congruent
• Trapezoid
Four sided polygon
360 degrees
Top and bottom are parallel, sides aren’t
• Parallelogram
Four sided polygon
360 degrees
Opposite sides are parallel
Opposite angles are congruent
• Circle
The side is always one set distance from the center
360 degrees
No angles
• Cylinder
3-dimensional figure
2 Parallel congruent base ends are circles
Curved lateral surface connects bases
• Sphere
The side is always one set distance from the center
One smooth curved lateral surface
• Dodecahedron
Twelve-sided 3-d figure
