Question

Please help!!!!! ASAP!!!

Answer 1

that's just the distance between 2 points
the distance between (x1,y1) and (x2,y2) is

`D= √((x2-x1)^2+(y2-y1)^2)`

we can find the distance between S and Q or P and R

S and Q is (0,0) and (a,b)


`D= √((a-0)^2+(b-0)^2)`

`D= √(a^2+b^2)`

distance between P and R is between(0,b) and (a,0)

`D= √((a-0)^2+(0-b)^2)`

`D= √((a)^2+(-b)^2)`

`D= √(a^2+b^2)`


`√(a^2+b^2) = √(a^2+b^2)`
so the lengths of diagonals are congruent
