Question 750230
The 2 points have y=4 and y=-4.
They are on the line {{{x=3}}}.
Their coordinates are (3,-4) and (3,4).
Each one forms a right triangle with other vertices A(0,0) and (3,0)
{{{drawing(300,300,-3,7,-5,5,
grid(1),
blue(triangle(0,0,3,0,3,4)),blue(rectangle(2.8,-0.2,3,0.2)),
blue(triangle(0,0,3,0,3,-4)),blue(circle(3,4,0.2)),
blue(circle(3,-4,0.2)),locate (-0.5,0,A)
)}}} The legs of those right triangles have lengths {{{3}}} and {{{4}}}, and the hypotenuse has length {{{5=sqrt(3^2+4^2)}}}
