Line n is a transversal. And now we have two corresponding angles are congruent. We assumed that from the get-go that we could find two quadrilateral, where these two corresponding angles are congruent. But if you have two corresponding angles congruent like this, that means that these two lines must be parallel.Pythagoras's Proof. Given any right triangle with legs a a and b b and hypotenuse c c like the above, use four of them to make a square with sides a+b a+ b as shown below: This forms a square in the center with side length c c and thus an area of c^2. c2. However, if we rearrange the four triangles as follows, we can see two squares inside the ...There are 5 basic ways to prove a quadrilateral is a parallelogram. They are as follows: Proving opposite sides are congruent. Proving opposite sides are parallel. Proving the quadrilateral’s diagonals bisect each other. Proving opposite angles are congruent.
