Plane

Plane

  • A flat surface that continues with out end in all directions


Dimension

Dimension

  • A measurement along a straight line of a length, height, or width of a figure


One dimensional

One dimensional

  • A measure with only one direction such as length


Two dimensional

Two dimensional

  • A measure with 2 dimensions, such as, height and width


Angle

Angle

  • Two lines or rays that share an endpoint


Vertex

vertex

  • The shared endpoint of two lines or rays


Degree

degree

  • The unit used to measure angles

90 degrees


Acute angle

Acute angle

  • An angle less than 90 degrees


Right angle

Right angle

  • A 90 degree angle


Obtuse angle

Obtuse angle

  • An angle more than 90 degrees


Intersecting lines

Intersecting lines

  • Lines that cross each other


Parallel lines

Parallel lines

  • Lines that never intersect and are the same distance apart


Perpendicular lines

Perpendicular lines

  • Lines that intersect at 90 degree angles


Dimension1

dimension

  • A measurement along the straight line of a length, height or width of a figure


One dimensional1

One dimensional

  • A measure with only one direction such as length


Two dimensional1

Two dimensional

  • A measure with 2 dimensions, such as, height and width


Three dimensional

Three dimensional

  • A measure with three dimensions, such as, height, width, and length


Clockwise

clockwise

Moving in a circular path to the right – like the hands on a clock


Counterclockwise

Counterclockwise

  • Moving in a circular path to the left – opposite from a clock


Diagonal

diagonal

  • A line that has a slope or angle


Horizontal

horizontal

  • A flat line like the horizon, which is left to right


Line of symmetry

Line of symmetry

  • A line that divides a figure in half so that the 2 halves can be folded on top of each other


Reflection

reflection

  • the movement of a figure to a new position by flipping the figure over


Rotation

rotation

  • The movement of a figure by rotating the figure around a point


Transformation

transformation

  • any movement of a figure (could be a translation, rotation or reflection)


Translation

translation

  • Moves a figure to a new position by sliding it


Symmetry

symmetry

  • Any shape that has symmetry has at least one line of symmetry
