Which statement is true about the lengths of the sides? Each side has a different length. Two sides have the same length, which is less than the length of the third side. The three sides have the same length. The sum of the lengths of two sides is equal to the length of the third side.

Two sides have the same length, which is less than the length of the third side

Step-by-step 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  

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
