Question

in the figure it is given that BC is equal to C and angle 1 is equal to angle to prove that triangle gcb is equal to triangle ABC is congruent

Answer 1

here is your answer follow me please

Answer 2

In triangle BCG and ECG
BC=CE(GIVEN)
ANGLE BCG= ANGLE ECG ( vertically opposite angles)
since angle 1 =angle 2
therefore 180 - angle 1 =180 - angle 2

SO TRIANGLE BCG IS CONGRUENT TO TRIANGLE ECG BY ANGLE SIDE ANGLE RULE
