In the Fig. 5.8, we have ∠1 = ∠3 and ∠2 = ∠4. Show that ∠Given: ∠1= ∠3 …(i)and ∠2 = ∠4 …(ii)According to Euclid’s axiom, if equals are added to equals, then wholes are equal.On adding Eq. (i) and (ii)∠1 + ∠2 = ∠3 + ∠4⇒ ∠A = ∠C
Given: ∠1= ∠3 …(i)
and ∠2 = ∠4 …(ii)
According to Euclid’s axiom, if equals are added to equals, then wholes are equal.
On adding Eq. (i) and (ii)
∠1 + ∠2 = ∠3 + ∠4
⇒ ∠A = ∠C
