How to make a perpendicular bisector.

                                            This is how to make a perpendicular bisector

1. Open the compass to just over halfway of line segment
2. Sharp point at point A makes an arc
3. Sharp point at point B make an arc
4. With ruler join the 2 intersectims of the arc.                  For example the points.

  Hope This Helped!                                                           A-----------o-----------B

Math: Integers

Main Definitions: 


- Integers: Are sets of numbers, there opposites and zero. These numbers are whole numbers. 
Example: (1,2,3,4...)  (...-4,-3-2-1) <<Negative numbers and Zero


- Opposite Pairs: Have the same number, but different signs.
Example: (-6,+6) or (-5, +5)


- Zero Pair: Are 2 integers that equal zero, 
Example: (+1,-1) = 0


- Oppisite Integers: (+6, -6) = 0   or   6+(-6) = 0

Learning about mode, with question and answer!

Mode-The most frequently ocurring number in a set of data.
Or if you still don't understand for short (The number that appears the most!)

Now for a question! for example:

Mode of  3, 5, 7, 7, 9               Answer: The mode is 7 since they appear the most.

Here's a 2nd question than incase you don't get it.

Mode of  2, 2, 4, 6, 6, 8, 11     Answer: The mode is 2 and 6  (Note: There can be more than one mode!)

Here's a 3rd question to make sure you understand.
 
Mode of 4, 6, 9, 4, 6, 8, 23      Answer: The mode is 4 and 6.

How To Make A Perpendicular Bisector

How To Make A Perpendicular Bisector
1) Open compass to just over halfway of the line segment.
2)Sharp point at point A make an arc.
3)Sharp point at point B make an arc.
4)With a ruler, join the 2 intersections of the arc.

That's how to make a Perpendicular Bisector

New Circle Information

Circle Graphs (pi charts)- a graph made of a circle; a graph that represents data using sections of a circle.

Sector- is a section of a circle made up of 2 radii and an arc joining them.

EXAMPLE:

What percentage is the missing sector? 7%

TRY: 1000 kids were asked what type of music they like. Here's the result. How many kids like country and folk music?

Circles

Diameter is the distance across a circle through its centre

Some Examples:

Radius (radii is the plural) is the distance from the centre of a circle to its outer edge

Some Examples:

We can do the formula 2R=D this means that 2 radii are needed to make a diameter of a circle.
1/2 x D = R
D/2 = R
Example:

Geometry #1

Parallel Lines are lines in the same plain that NEVER touch.

2 Examples:
















Intersecting Lines are lines in the same plain that meet or intersect.

4 Examples:















Perpendicular are lines in the same plain that intersect at a 90 Degrees Angle

3 Examples:















Line Segment is a piece of a line with starting and ending points.

Example:















Try to name all the 7 line segments in this picture.
