Question

2. Give any two real-life examples for congruent shapes,
3. If AABS - AFER under the correspondence ABC FED,​

Answer 1

solv. Let A' be the 1st term d be the common difference Sn be the 1st sum of n term's be the given AP

Then, Sn = n {2a + (n-1) d}

2

A/Q

Sp = a

=> P {2a'+ (p-1)d} = a ——————>(1)

2

=> 1 {2a' + (p-1) d} = a ———————>(1)

sq = b

=> q {2a+(q-1)d} = 6

2

=> 1 {2a'+ (a-1)d} = 6 ——————(2)

2

and Sr=c

=> r {2a'+(r-1)d} = c

2

=> 1 {2a'+(r-1)d} = c ——————>(3)

2

LHS = a (q-r) + b (r-p) + c (p-q)

p q r

= 1 {2a

Aur nahi janta hu
