WebSince all the sides of a rhombus are equal, each side is 56 ÷ 4 = 14 units. We know that the diagonals of rhombus bisect each other at right angles. So, half of each diagonal and the side of the rhombus form a right-angled triangle. Using the Pythagoras theorem, the length of the unknown diagonal of the rhombus can be calculated. WebEvery rhombus has 4 congruent sides so every single square is also a rhombus. A square is a special rhombus that also has 4 right angles. Keep in mind that the question "Is a square a rhombus?" means Is …
