We don't even get a menu?  Man.

Transformations that are rigid motions are also called isometries.  They preserve size and shape.

Rigid Motions:

Translation

Rotation

Reflection

There's often another one called a

Glide Reflection

which is a combination of translation and reflection.

Not Rigid Motions:

Dilation

Obviously dilations change the size.  There are also transformations that distort the figure, for example scaling the coordinates differently.  Let's call them:

Stretching

Shearing

What is the average of 1/2 and 1/3
nadya68 [22]

Hi there!

In order to fin the average, you need to add all the terms together and then divide the result by the number of terms :

(\frac{1}{2} + \frac{1}{3}) ÷ 2 = average


Now, I’m assuming that you know that in order to add fractions, both fractions must have the same denominator (bottom number in a fraction). Since these fractions do not have the same denominator, we must give them one.


To find the lowest common denominator (which will help us solve this problem), we must find out what 2 & 3 go into. Well, both numbers go into 6!


So, if the denominator is now 6, you must multiply the numerator (numbers about the “/” line in this case are both 1) by how much you multiplied its denominator by.


For 1/2, you multiplied 2 by 3 to get 6. Therefore, you must multiply the 1 by 3 aswell.


for 1/3, you multiplied 3 by 2 to get 6. Therefore, you must multiply the 1 by 2.


and now you have 3/6+2/6 since the denominators are the same, you can add the numerators normally which gives you 5/6


\frac{5}{6} ÷ 2 = \frac{5}{12}


Your answer is : \frac{5}{12}


There you go! I really hope this helped, if there's anything just let me know! :)
