Question

abcd is a square prove that triangle aon is an issoceless​

Answer 1

Answer:

given: ABCD is a square..

Step-by-step explanation:

ABCD is a square... (given)

therefore, AB=BC=DC=AD... (property of square)

now, join diagonal BC we get an triangle ABC

IN triangle ABC already we had state that.,

side AB =side BC...

therefore, since two sides of triangle are congruent... then it is an isosceles triangle...

therefore ∆ ABC is an isosceles triangle...

hence proved
