Question

Each side of a rhombus is 10 cm long and one of its diagonals measure 16cm.The length of the other diagonal is

Answer 1

If we make diagonals in rhombus then it will make a right angle triangle as diagonal bisect at 90° , So

by using Pythagoras theorem we can find other diagonal...

diagonal bisect each other so it 8 - 8cm

so,

(hy)^2 = (b)^2 + (h)^2

(10)^2 = (b)^2 + (8)^2

100 = (b)^2 + 64

(b)^2 = 100 - 64

b = under root36

b = 6

then other diagonal is 6+6 = 12cm...
