Show that if a geometric figure is congruent to another geometric figure, which is in its turn congruent to a third geomtric figure, then the first geometric figure is congruent to the third.
Answer : I will be showing what the question asks by using superposition of the geometric figures (Wether it's in 1D,2D, or 3D)
First, we have 3 geometric figures : A, B, and C.
And also, we know that A is congruent to B and B is congruent to C.
So, : A==>B==>C
Now, let's show that A is congruent to B, that is : A==>C
We know that A is congruent to B and C is congruent to B. So this gives us two possible answers :
C is congruent to A or C is not congruent to A. Let's see what would happen if C wasn't congruent to A.
We know that two things which are equal to the same thing are equal together. A is congruent to B. C is congruent to B. But we said that C couldn't be equal to A. Again, we said that two things which equal the same thing are equal together. We now have a contradiction, so this is not the possible answer. The last choice is : C is equal to A, because A is congruent to B, C is congruent to B. So, two things which are equal to the same thing are equal together.
*I'm taking for granted that : Two things which are equal to the same thing are equal together. Will you accept it or not ?
Thank you and please tell me what you think.(I'm kinda new to it)
