The use of geometric spaces is very important in our lives In ancient times it was used many steps to resolve the area of the triangle, but this research is easy to solve the area of triangle with one side and two angles, and it saves time and effort and thinking Old is resolved rhombus area of a difficult steps, but in this research is easily the solution.
rhombus area half the multiplication of the two diagonals, but in the new area of the law in terms of diagonal and angle only Parallelogram area equal to multiplication the base to rise, but the new method uses diagonal and angles of the diagonal only Area of the rectangle equal multiplication length and width, new method uses diagonal and angles of the diagonal only And so easy to answer and Uses
1- triangle area in a new method 2- parallelogram area a new method 3 - rectangular area in a new method 4 - designated area in a new method 5 - square area in a new method
