Can you explain how to decompose a rectangle into congruent triangles? How does the area of the decomposed pieces relate to the area of the rectangle

I'm not sure about this, but here goes nothing..

Here's the definition to congruent triangles: Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.

So meaning that if you split them in half, (Depending on the way you turn it, and depending on the triangle) they would have to mirror each other to be equal to each other.

Now, for the other question, the triangle has to be a right triangle to make a rectangle. If you turn the triangle where the long side is facing the opposite of the other long side. If you put them together it makes a rectangle.

This may have not have answered the question, but I'm happy I tried to help.

Though if I did get it right, could I possibly have brainliest? U would be my first one.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
