Patterns
A repeating pattern has a set number of objects or numbers
that repeat the number, color, and shape
ABCABCABC
Growing patterns build on the beginning of the pattern, adding
to the pattern each time it repeats

Plane Figures and solid shapes
Face- the flat surface of an object. Objects can have no faces,
one face, or many faces!
Vertex (plural: vertices) the corner of an object- this is where 2
or more edges on a plane figure, or 3 or more edges on a solid
figure, meet in a point.
Edge: where the sides of two flat faces meet

LINES
Point: an exact place in space
.
Line: a set of points that create an endless line going in both
directions.
Line segment: a set of points on a line with two end points.
.
.
Ray: a set of point on a line with one end point and one end
going on endlessly in both directions.
.
Types of lines:
Parallel - two lines that run beside each other but never cross
intersecting: two lines that cross each other at one point
perpendicular: two lines that cross each other on a right angle,
creating a perfect square
Angles
An angle is made of two rays with the same
end point.
The end point is called the vertex.
Angles also have letters used to label each end of the ray. The
middle letter is the vertex. You can label the angle two ways.

Congruent Shapes
Congruent Shapes have the same SIZE and same SHAPE
Similar shapes are the same shape but have different sizes
Symmetry
Both sides of an object are equal in size, shape, and
content.
The object can be folded on the line of symmetry and
both sides will be the same.

Translations: You can have a flip, a slide or a turn.
