Height of a Triangle

Height of a Triangle

Here is an example of the height of a triangle:

Height of a Triangle is a perpendicular line from base to opposite angle.

Parallelogram

Heres and example of an parallelogram:

A Parallelogram is a four sided Figure with opposite sides Parallelogram

and equal in length.

Angle Bisector

And Example of An Angle bisector:

(angle ABC)

This is an Angle Bisector.

And angle Bisector is a line that Divides an angle into two equal parts.

-Equal angles are marked with the same angle.

Steps To make an "Angle Bisector"

1. Compass point at the angle vertex make an arc through both arms.

2. Compass point at the vertex of your first arc and make one arm make another arm.

3.Repeat step 2. But from the other arm.

4.Draw line from arc intersecting to angle vertex

Perpendicular Bisector

Perpendicular Bisector  

This is a picture of an perpendicular bisector

A perpendicular Bisector is a line that divides another line segment in half and meets at right angle.

-Equal line segments are hash marks.

How to make a Perpendicular Bisector

1. Open compass to just over half way of a line segment.

2. Sharp point at "A" Make an Ark

3. Sharp Point at "B" make and Ark

4. With ruler join the two intections

ACUTE ANGLE

The measure of an angle with a measure between 0° and 90° or with less than 90°.

More examples in the pictures too.

Equivalent Fractions

you multiply or divide both the top and bottom by the same number

You can multiply any number to keep its value...

What ever you do the top you do to the bottom!

Or

What ever you do to the bottom you do to the top..

It never changes

Subtracting Mixed fraction

Mixed fraction

A Mixed Fraction is a whole number and a proper fraction
combined. Not in improper... It wont be a mixed fraction them.

Improper fractions

Like: 10/8 ←

Lowest common denominator

L.C.D. is the smallest positive integer that is a multiple of the denominators.

Example:
5/12 , 11/18 =36

Becuase its the least common multiple of 12 & 18!

G.C.F

The greatest common factor is the largest number that can divide a numbers evenly

18- 2x2x3

24-2x2x2x3
=
common=
2,3
the greatest is 3

Question/Answer 7

Textbook 214-216

Number 7#

Write each addition statement shown

by the diagrams. Then add. Write your

answer in lowest terms.

Eg. two eights + two eights =four eights just add on the top not on the bottom.

Bar notation...

Write repeating decimal with a bar notation.

How I did it? :

I did it like this what it says on the picture!

every repeating decimal doesn't stop! so a shorter way to say it is put a bar notation on the top!

Like this... --- ←

o.5555555= o.5 ←

The solution is:

where to put the bar notation!!

and a shorter way to make it.

Its and easier way!!
