## The total amount of angles in a
triangle equals 180'altogether.

## To find a missing angle in a pentagon you
add the numbers you all ready know,
which equals 140+140+110+100+__=
540'. Then after adding those numbers
say 540-490= 50

## How to draw a equilateral triangle with a
compass and protractor. With the angles
all 60' each.

## A square has 2 triangles and
a pentagon has 3.

## A octagon has 1080', and a
decagon has 1440'.

## A heptagon has 5 triangles
and adds up to 900'.

## I learned about co-ordinates, how to write them and
what they are. When writing them you write the
number that goes across then the number going up or
down.
