Question

in the given figure it is given that angle 1 is equal to angle 4and angle 3 =angle 2.by which Euclid's axiom it can be shown that if angle 2= angle 4 then angle 1 = angle 3​

Answer 1

Answer:

∠1=∠3

∠2=∠4

$$_____________$$

∠1+∠2=∠3+∠4

From 1st postulate of Euclid,

The things which are equal to equal this are equal to one another.

⇒∠1=∠2

⇒∠1=∠2=∠3=∠4
