Question

in given figure ABC is equal to 90 degree and BD is equal to perpendicular to AC then ab is equal to 8 cm CD is equal to 2 cm length of the BD is​

Answer 1

Answer:

BD = 4 cm

Step-by-step explanation:

ΔABC is an right angled triangle and AC is the hypotenuse.

hence BD ⊥ AC,

so BD is a perpendicular to the hypotenuse and A-D-C

So BD² = AD x DC

  (bcoz property of geometric mean)

BD² = 8 x 2

BD² = 16

Therefore BD = 4 cm
