Essential Question: How do I use properties of Congruence to find unknown values?

First  you must and need to know what congruent figures are. Congruent figures are figures with the same amount of sides and there angles are all the same. Here is an example:

 4x + 5= 105
      -5     -5
4x = 100
4       4
x = 25
The answer is x =25
