Let x represent the number of hours you read a book and y the total number of pages you have read, You already read 70 pages and can 30 pages per hour. Write an equation relating x hours and y pages you read, Then predict the total pages you will have read after another 3 hours.

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.
