In unit square abcd, m is the midpoint of ab and n is the midpoint of ad. what is the area of triangle mnc

i belive those are the ones that are under 90 degreese.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to

pls mark as brainliest
