To do a two-column proof, you must know the definitions of the terms that are being used. Also, you must know the postulates and theorems you have learned so far. You look at the given information, and using the definitions, postulates, and theorems, you reason in your mind how to go from the given to the conclusion, step by step. You write each step and the accompanying reason that allows you to conclude each step.
Answer:
201.06ft^2
Step-by-step explanation:
The formula for the area of a circle is pi*r^2
We just plug in 8 for r and we get our answer.
5:9
You need to find the greatest common factor and divide each side by it.
In this case it is 10... 50/10 = 5 90/10 = 9
So 50:90 = 5:9
As stated by the statement, isometric means same measure. So, when a rigid transformation occurs all the measures of the original figure (which will be transformed) will be the same of the new figure (the result of the transformation).
That means that you can verify that the transformation used was rigid by checking the measures of both (original and transformed) figures: if and only if the meausures of the final figure are the same of the original figure the transformation was rigid.
