Question

ABCD is a llgm whose diagonal intersect eaxh other at right angles. If the length of the diagonal is 6&8cm, find the length of all the sides of the llgm.​

Answer 1

let ac and bd bisect each other at o. then oa=3cm and od=4cm

in triangle aod,

(3)^2+(4)^2=(ad)^2

9+16=(ad)^2

25=(ad)^2

ad=5 cm

therefore,

each side of parallelogram will equal to 5 cm.
