a^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse

Answer:

B .[tex](20)^2+(21)^2=(29)^2[/tex]

Step-by-step explanation:

We are given that

Three sides of given triangle are 21, 20 and 29.

If a triangle is right triangle, the triangle satisfied the pythagorous theorem.

Pythagorous theorem:

[tex](hypotenuse)^2=(base)^2+(Perpendicular\;side)^2[/tex]

[tex](29)^2=841[/tex]

[tex](20)^2+(21)^2=400+441=841[/tex]

Hence , [tex](29)^2=(20)^2+(21)^2[/tex]

Answer: B .[tex](20)^2+(21)^2=(29)^2[/tex]
