formulate an argument to prove that all squares and circles are similar

Solutions

Expert Solution

A circle is the set of points equidistant from a given point. Consequently, a circle is defined by only the radius.
Proof:
• Move the center of the smaller circle onto the center of the larger circle. Translate circle B, by vector , onto circle A. The circles are now concentric (they have the same center).

• A dilation is needed to increase the size of circle B to coincide with circle A.
A value that when multiplied by r1 will create r2 is needed.

The scale factor, x, to increase circle B:
         
• A translation, followed by a dilation with scale factor will map one circle onto the other, thus proving that the circles are similar.

• We found the similarity transformations!

Similarly we can prove the same for the square also . :)

Exercise 1.13.5: Determine and prove whether an argument in English is valid or invalid. Prove whether each argument is valid or invalid. First find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates. If the argument is valid, then use the rules of inference to prove that the form is valid. If the argument is invalid, give values for the predicates you defined for a small domain that demonstrate the argument...
