      @@princeyadav8710 Bro Dekho mai batata hu ke ye kha se aya hai Listen carefully.
      We know that We take sign of height of object and image in order of principal axis means Jo principal axis ke upar hoga wo positive and jo principal axis ke neeche hoga wo negative only in terms of height of object and image. So agar hmmh diagram me dekhe similar triangle wale me jo mirror derivation hai usme object image is positive and image formed is negative which means - Hi/Ho
      ALSO distance of object is taken from pole of mirror this is important from pole of mirror .So distance of object I.e U is negative and also distance of image i.e V is also negative which can be written as -V/-U minus minus gets cancel therefore we have V/U .
      Now compare ratios of sides .
      - Hi/Ho= V/U
      Hi/Ho= -V/U
