Question

9) ABCD is a parallelogram: If LA
= 70°, calculate LB, LC and LD
​

Answer 1

Answer:

<A=70 DEGREES

<B=110 DEGREES

<C=70 DEGREES

<D=110 DEGREES

Step-by-step explanation:

<A =70

THEREFORE, <C=70  (OPPOSITE ANGLES OF A PARALLELOGRAM ARE EQUAL)

<A+<D=180( ADJACENT ANGLES OF A PARALLELOGRAM ARE SUPPLEMENTARY  )

70+<D=180

<D=110

<D=<B=110 (OPPOSITE ANGLES OF A PARALLELOGRAM ARE EQUAL)

THEREFORE,

<A=70 DEGREES

<B=110 DEGREES

<C=70 DEGREES

<D=110 DEGREES
