The amusement park won’t allow kids to ride roller coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inches every month. How many months will it be until Michael can ride a roller coaster? (Solve with inequalities and solve for x)

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.
