Question

ABCD is a rhombus . AC is a diagonal.
1) Show three pairs of equal parts,giving reason.
2)Is triangle ABC= congruent triangle ADC? Give reason.
3) Is angle BAC= congruent angle DAC? Give reason.

Answer 1

Given  : ABCD is a Rhombus

=> All sides are equal in length (AB=BC=CD=DA)

=> Opposite angles are equal while adjacent angles are Supplementary

   ∠DAB = ∠BCD , ∠ABC = ∠ADC

=> diagonals bisect each other perpendicularly

In ΔABC and ΔADC,

AB=CD (given)

BC =AD (given)

AC=AC..... (common side)

∴ΔABC≅ΔADC

∠BAC = ∠DAC (As AC is a diagonal of Rhombus and diagonals bisect the angles.)
