Can someone help me with geometry about finding the lengths of diagonals?

Question

anonymous · Answer

ask Pythagoras

anonymous · Answer

Who is that?

anonymous · Answer

pythagoreas theorem, a^2 + b^2 = c^2

c is the long side, a and b are the straight sides, this only works with right triangles

anonymous · Answer

I dont understand? Im doing a quiz and it is asking me "Find the lengths of the diagonals of this trapezoid"

anonymous · Answer

@parot

anonymous · Answer

is it isosceles?

anonymous · Answer

isosceles means that it the sides are parallel.

btaylor · Answer

can you show us the problem?

anonymous · Answer

yeah its

anonymous · Answer

sorry @parot i didn't understand

btaylor · Answer

So, the diagonal will be the line segment from (-a,0) to (b,c)
You can use the distance formula for this.

anonymous · Answer

@Camibayybee  it doesn't matter anyways since you have variables, so it wouldn't work.

anonymous · Answer

Wait so is that all i have to find or do i still have to find other diagonals @BTaylor

btaylor · Answer

because the trapezoid is isoceles (both slanted sides are congruent), the diagonal lengths are the same.

btaylor · Answer

so...yes.

Oh wow thats pretty easy lol, Thanks! @BTaylor @parot
