Diagonals of a rhombus are 6cm and 8 cm. Find the length of the side of the rhombus.

Answer 1

Because all sides of a rhombus are the same length, you only need to find one side. The diagonals divide the rhombus into 4 equal right triangles.
The diagonals/2 give length of two of the triangle sides. So one side will be 3 and the other 4. Use the Pythagorean Theorem to solve for the hypotenuse. The hypotenuse is equal to to side length.
