Prove that when x>1, a triangle with the side length a=x^2-1, b=2x, and c=x^2+1 is a right triangle. Use the Pythagorean theorem and the given side links to create an equation use the equation to show what does triangle shows the rule describing right triangles. Explain your steps.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
