प्रश्न

In the below Fig, ABCD and PQRC are rectangles and Q is the mid-point of Prove thaT

i) DP = PC (ii) PR = `1/2` AC

Advertisements

उत्तर

(i)In DADC, Q is the midpoint of AC such that

PQ || AD

∴ P is the midpoint of DC

⇒ DP = DC        [Using converse of midpoint theorem]

(ii)Similarly, R is the midpoint of BC

∴ PR = `1/2` BD   [Diagonal of rectangle are equal \BD = AC ]

PR = `1/2` AC
