I believe the diagonals would be perpendicular. So if it's on a graph/coordinate plane the slopes would be opposite. And all the sides would be the same length/2 sets are parallel/same slope

Answer:
sure
Step-by-step explanation:
1) line up 641 and 63
    641
x__63_
2) multiply 3 by 1 then 4 then 6 and carry the tenths place number if there is one
   1 
   641
x__63_
   1923
3) add a zero under the 3 to hold the ones place and multiply 6 by 1 then 4 then 6 and since we’re working with the tenths place now and dont forget to carry numbers if you need to
      2 
      641
   x__63_
      1923
   38460
 4) add your two numbers together
     1 1     
     38460
+___1923_
      40383
so that is your answer “40383”
