Question

If the slope of angle beatline BC is 2/3 and the slope of CD is -1/2 find the slope of AD

Answer 1

we know that

A parallelogram has two pair of congruent and parallel sides

so

AD=BC

AB=CD

and

AD is parallel to BC

AB is parallel to CD

so

the slope of AD is equal to the slope of BC

therefore

the slope of AD is 2/3
