Given: ΔABC ~ ΔPQR. &

ar ΔABC =ar ΔPQR

To Prove: ΔABC ≅ ΔPQR

Proof: Since, ΔABC ~ ΔPQR
ar ΔABC =ar ΔPQR. (given)

ΔABC / ar ΔPQR = 1

⇒ AB²/PQ² = BC²/QR² = CA²/PR² = 1

[ USING THEOREM OF AREA OF SIMILAR TRIANGLES]

⇒ AB= PQ , BC= QR & CA= PR

Thus, ΔABC ≅ ΔPQR
[BY SSS criterion of congruence]

Aap educart solve kar rahe ho ??

Yogita Ingle 6 years, 2 months ago

HCF of 404 and 96

404 = 2×2×101

96 = 2×2×2×2×2×3

Common Factors = 2×2

HCF of 404 and 96 = 4

LCM of 404 and 96

404 = 2×2×101

96 = 2×2×2×2×2×3

LCM = 2×2×2×2×2×3×101 = 9696

LCM of 404 and 96 is 9696

HCF × LCM = Product of the two numbers

⇒ 4×9696 = 404×96

⇒ 38784 = 38784

LHS = RHS

Hence, it is verified.

Taking RHS take cos (2cos2-1)tan But tan can be written as sin÷cos Cos(2cos2-1 ) ×sin ÷ cos Cos canclled with cos thus it is sin (2cos2-1) Now take LHS sin(1-2sin2theta) Sin (sin2+cos2-2sin2) ,1 = sin2+cos2 Sin (cos2-sin2) Sin (cos2 -1+ cos2) Sin (2cos2-1 ) Thus lhs = rhs hence proved
