Geometry

LI: To define geometry terms.

LI: To understand the properties of 2D shapes.

Define the following geometry terms then draw an example.

	Define	Draw
congruent	When one shape can become another using Turns, Flips and/or Slides.
angle✓	Connecting one line to another line
side✓	A side is the line around the edge.
vertex✓	Is a pointed finger on the edge.
vertices✓	Is a corner where the edge meets.
line segments✓	The part of a line that connects two points.
parallel✓	A line that always has a straight line that is distance apart.
perpendicular	A 90 degrees line that gives a line,place or surface.
diagonal✓	A straight line that connects to a vertex.
radius✓	A straight line from the center.
circumference✓	The distance around the edge.
degree✓	A measure angle that has 350 degrees.
plane ✓	a plane is a flat, two or more-dimensional surface.
solid✓	A body that has three or more dimensions.
perimeter✓	The distance around the side
area✓	The amount of space inside the boundary of a flat

acute✓	Acute angle is less than 90 degrees.
obtuse✓	Is an angle that is 150 degrees.
straight✓	Has a straight line that is 180 degrees.
reflex✓	Is an angle that is more than 180 degrees and less than 360 degrees.
right angle✓	Is an angle that is 90 degrees.
full rotation✓	Is a full rotation means spinning around 360 degrees.
