The velocity of a body as a function of time is given as v (t) = 5e-2 +4, where is 't' is in
seconds, and 'v' is in m/s. The acceleration in m/s2 at t= 0.6 seconds is

0 -3.012
O 5.506
04.147
0-10

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
