How would you use estimation to evaluate this expression: 10.2 × [(2×3.7)+8]

How to choose the sign of the radical in the denominator of the formula for the distance from a point to a line.

Why is studying fractions important

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.
