Plz hurry, brainliest and lots of points plz explain answer and only answer if you are actually gonna do it.
the line segments graphed on the coordinate plane represents an attic truss which uses triangular supports in the corners to provide the necessary structural strength, while providing a space for storage. due to structural concerns the designers have opted for a low ceiling. the interior boards of this truss are called webs. these web boards have been used to create two triangles as can be seen on the graph below.

note: use the graph on the left to answer the questions below. the diagram on the right has been provided for reference.

(a) does each triangle have the same starting coordinates? explain.
(b) does each triangle have the same ending coordinates? explain.
(c) does each triangle have the same change in x-values? explain.
(d) does each triangle have the same change in y-values? explain.
(e) does each triangle have the same ratio of change in y-values over change in x-values? explain.
