Question

angle 3 angle 1 angle 4 +angle 1 angle 3 angle 4 =?​

Answer 1

Step-by-step explanation:

Let angle 1 = a

angle 2 = b

angle 3 = c

angle 4 = d

Given:a=d, b=d, b=c

T.P.T:a=d

Proof: b=d (given)

a=d

Therefore a=d

Since b= c

and b= d

Therefore c=d

By 1 and 2

a=c

The axiom used is the things equal to same things are equal to one another

Answer 2

Answer:

Let angle 1 = a

angle 2 = b

angle 3 = c

angle 4 = d

Given:a=d, b=d, b=c

T.P.T:a=d

Proof: b=d (given)

a=d

Therefore a=d               -------1

Since b= c

and b= d

Therefore c=d    ----------2

By 1 and 2  

a=c

The axiom used is the things equal to same things are equal to one another
