Cartesian planes
patterns and plotting dots
interpreting graphs
i can not really say anything on this because it is hard to write on
you have to lie down to get up
x is 1st before y
UNITS OF LENGTH
100cm=1m

perimeter
There is no height
area =LxW
Calculate like it was a normal square or rectangle
AREA OF TRIANGLES AND COMPOSITE SHAPES
LxW
LxWxH
1000m=1km
10mm=1cm
perimeter is L+H
a line shows the measurement is the same
No height

Lines mean the same measurement
Number sentences
they can be right and sometimes wrong... check
introduction to equations
letters such as x can be replaces for a number
WESTSIDE DOES NOT DO THIS
solving equations using the balance method
solve like normal

Classifying angles
right angle: a angle that is 90 degrees *hink if it has a box in the corner it is a right angle
if it has a box it is a right angle
obtuse: an angle larger than 90 degrees but is below 180 degrees
acute: a angle under 90 degrees
straight angle: a angle that is 180 degrees that makes a straight line
reflex angle: a angle bigger that 180 degrees but smaller that 360 degrees
revolution: a angle that is 360 degrees
calculating angles
supplementary angle: more than one angle that makes 180 degrees
to find x have the total angle and subtract the other angles in it
complementary angles: when more than one angle ends up making 90 degrees
angles and parallel lines
parallel lines: lines that are straight and will never touch it the line is extended
corresponding angles: angles that are equal that are traversal that are on the same side eg. both left.... but one is above and the other below
alternate angles:the angles are the same that have a traversal and are on opposite sides
traversal: a line drawn through (intersects) a pair of lines
co-interior angles: angles that are not equal but are supplementary
polygons
2D shapes
the shapes do not have to be perfect to be a specific l type only needs the amount of sides
to be a polygon it needs a minim of 3 sides
