Math History
Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

Congruent angles exactly the same size and shape. They have the same measurements. For example, two angles are congruent if they both measure 85 degrees, or if they both measure 621 degrees. As long as they have the exact same measurement, angles are congruent. But they do not have to be the same length and width.
The definition of congruent is:
con·gru·ent /kənˈgro͞oənt/Adjective:
- In agreement or harmony.
- (of figures) Identical in form; coinciding exactly when superimposed.
As noted with the mathematical example above, they are identical angles. If you put two congruent triangles over one another, they will look the same.
In a cube, all sides if sliced off from each other until they are each 2D squares, will all be congruent.
What is the relationship between scale factor and perimeter?
It is a strict linear relationship. Double the size, double the perimeter. The area, however, increases by the square of the scale factor.
What is the name of a 16 sided polygon?
A 16-sided figure is known as a hexakaidecagon, 16(sixteen)-gon, or hexadecagon.
we use them in situations that involves going in between numbers!
When you're out buying food for a group of people, or sharing something, you'll want to share it equally... So, say you were buying a large pizza for 4, and it cost $10, you'd have to do 10/4 to know the exact amount that each of you is to pay to make it fair...
How do you figure out distance?
A 1/2 diameter piston moves 10 inches with 30 lbs force how far will it move with 6 inch diameter piston and how much weight will it lift
How old would you be if you were born in 1975?
Take the current year and subtract the birth year to get their age. Then, you will get a number which is their current age, or the age that they will turn this year. * 2009 - 1975= 0034 With this information, you could even do this: * 2009 - 33= 1975 But, you already knew the year that the person was born in.
2011-1975 = 36
Who created and invented the multiplication sign?
Multiplication is invented by Human. Maths is not invention of single individual. Many Mathematicians around world discovered and invented new things and added them into Maths.
What are three consecutive odd numbers that equal -99?
Lets substitute the first number by -x(so x has a positive value), so the next two consecutive odd numbers would be (-x-2) and (-x-4). Then, put it all into an equation: -x+(-x-2)+(-x-4)=-99 -3x-6=-99 -3x=-99+6 x=-93/-3 x=31 so the next two numbers would be (-x-2) which equals (-31-2)=-33 then (-x-4)= (-31-4)=-35 So at last the three conecutive odd numbers are: -31, -33, -35 and to check your work you can add them up (-31)+(-33)+(-35)=-99
If you are driving 60 miles per hour how long would it to drive 459 miles?
Well, 50 miles in a mile every 1 and 12 seconds, so in minutes is 550 mins 48 secs or 9 hours 10 mins and 48 seconds...Sorry I love being so precise with answers :)
What is the origin of the expression plus one?

Addendum:
It's also possible that this question refers to the phrase as used on invitations - where the invitation is for the recipient and their guest. It can be used when you wish to invite someone to a function and aren't sure of who they're currently seeing...
