Question

ABCD Is a rhombus
Prove that ∆le ABC is congruent to ∆le ADC​

Answer 1

Answer:

* all sides of rhombus r equal so AB = AD and BC = DC

* opposite angles of rhombus r equal so angle ABC = angle ADC

so triangle ABC = triangle ADC by SAS test of congruency

Explanation:

Mark me as brainliest !!!!!!!!

Answer 2

Explanation:

AB = BC(All sides of rhombus are equal)

ang. ABC = ang. ADC (Opposite angles of a rhombus are equal)

AD = DC (All sides of rhombus are equal)

Thus, ∆ABC is congruent to ∆ ADC (SAS axiom)
