Question

please help me .Who answers first I make them as BRAINLIEST​

Answer 1

Answer:

1>.three pairs are AB=CD(opposite side of a rhombus are equal.

AD=BC (opposite side of a rhombus are equal.)

angleB=angleD (opposite angles of a rhombus are equal.

2>.given=ABCD is a rhombus.

Prove:ABC congurent ADC.

PROOF:in triangles, ABC and ADC;

AB=CD (opposite side of a rhombus are equal.

BC=AD (opposite side of a rhombus are equal.

AC =AC (common)

so, ABC congurent ADC (by sss congurence).

3>. As ABC congurent to ADC.

therefore, by CPCT angle BAC=angle DAC.
