The nile is 4,160 miles, about how many miles of the nile are actually in egypt?

650 miles

Step-by-step explanation:

River Nile transverses different countries in Africa, from Lake Victoria where it begins. Although R. Nile is 4160 miles longs, only 650 miles pass through the ancient Egypt. Beside Kenya, Uganda and Tanzania that border Lake Victoria, the Nile passes through countries like Rwanda, Burundi, Eritrea, Democratic Republic of Congo, Ethiopia and South Sudan. When in Egypt, River Nile starts at the first cataract to the delta where it deposits its water into Mediterranean sea.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
