Answer:
Two sides have the same length, which is less than the length of the third side
Explanation:
The attached figure shows that the two lengths has 45 degrees each and one length is right angle i.e. 90 degrees
So as per the given options, the second option is correct
As the first option is wrong because two sides contain the same length and one side has a different length
The third option is wrong
The fourth option is also wrong because as per the Pythagorean theorem the square of the two sides should be equivalent to the square of the hypotheses
Therefore the second option is correct
