If one diagonal of a rhombus is equal to its side, then the diagonals of the rhombus are in the ratio of:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. .
Let the side of the rhombus = a and one diagonal (d1) = a (Same length)
On applying Pythagoras' theorem, the second diagonal = √(4a2 - d12)
= √(4a2 - a2)
= √(3a2)
= √3a
Ratio of first and second diagonal = a : √3a = 1 : √3
The diagonals of the rhombus are in the ratio 1 : √3.
