Question

*Which of these options must be true for a parallelogram to be a rhombus?*

1️⃣ Its adjacent sides must be equal
2️⃣ Its adjacent angles must be equal
3️⃣ One of the angles must be 90°
4️⃣ All the angles must be 90°

Answer 1

Here’s your answer mate—


“Only the first option needs to be true for a parallelogram to be a rhombus.”

Second is false, if adjacent angles are equal it might become a rectangle. Similarly in condition 3 and 4 we face same scenario. We might get a rectangle if we follow 2 3 or 4th option.
