Question

Angle 1 = angle 3 and angle 2 = angle 4 show that angle A = angle c, using appropriate Euclid axiom.

Answer 1

LOOK 
ANGLE 1 = 3                           - 1 EQUATION
ANGLE  2 = 4                           - 2 EQUATION

SO LET ANGLE 1,2,3,4 ANGLE A,B,C,D
SO IN EQUATION 1 ANGLE 1= 3
NOW  = A =C

Answer 2

Step-by-step explanation:

Angle 1= Angle 3

Angle 2= Angle 4

Since, Things which are double of same thing are equal to one another

Therefore,

Angle 1= Angle 2+ Angle 3 Angle 4

Hence, Angle A= Angle C
