Answer:

Make sure that all words are spelled correctly.

Try different keywords.

Try more general keywords.

Try fewer keywords.

Answer 2

by using mid point formula...

$x = \frac{x1 + x2}{2} ... \: y = \frac{y1 + y2}{2}$

we know that the diagonals of a parallelogram intersect each other...so, the mid of them are same...

take diagonals nd put value of points in the formula...

otherwise use YouTube there is very good explanation!!...❣️

hope!!...it helps uhh...❣️
