Did Pythagoras have any children?

November18

We are not certain if Pythagoras had any children but he had several well known triplets – here are three of them! See more Pythagorean Triplets here! (H3 Note: we are often responsible for the poor humor on this site)

Jesus and the 345 Triangle of Pythagoras

March29

A question which caught my attention recently was, “Would Jesus Christ (the carpenter from Galilee) have used the 3,4,5 Triangle property from the Pythagoras theorem for right-angled triangles?” Most carpenters and home handymen use this regularly to square walls, etc. What do you think?

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
