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
Perpendicular Lines
• Intersect at a 90 degree angle
Parallel Lines
• Never intersect• Extend forever
Triangle
• Three sided polygon• 180 degrees
Right Triangle
• 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• Made of pentagons• 3 faces meet at each vertex
Decahedron
• 10 sided 3-d figure• Made of triangles
Cube
• Six- sided 3-d figure• All sides, angles, and edges are congruent
