Answer 2

Answer:

The diagonals of a rhombus are perpendicular to each other making 4 right triangles when they intersect each other at the centre of the rhombus. Step 2: Find the length of diagonal 2, i.e. d2 which is the distance between B and D. Step 3: Multiply both the diagonals, d1, and d2. Step 4: Divide the result by 2. The Perimeter of a rhombus is the total distance travelled along the border of a rhombus. So the formula to calculate the perimeter of a rhombus is: P = 4 × a (where 'a' is a length of side of rhombus The dual polygon of a rhombus is a rectangle: A rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. ... The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.
