@phi Please help

phi · Answer

if you divide each figure into two triangles and show each triangle is congruent by side-side-side, to the corresponding triangle in the other figure, that would prove the figures are congruent.

anonymous · Answer

That is what I say in my own words or do I have to do it too??

phi · Answer

that is how to show the figures are congruent.
but then you have to do the work.

the length of each side  can be found using the distance formula.
do you know how to do that ?

anonymous · Answer

d= sqrt(x_2-x_1/y_2-y_1)?

anonymous · Answer

I totally forgot but I know it is something like that

phi · Answer

the idea is based on the pythagorean theorem
a^2 + b^2 = c^2

where a and b are the legs  and c is the hypotenuse

phi · Answer

the formula tells you how to find the length of each side using the coordinates
but in your graph, we can just count.

phi · Answer

For example the leg from point A to point D
