yes- see explanation

Explanation:

# color(blue) " Pythagoras' theorem " " states " #
'the square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides'

The Converse of this statement is that if the square on the longest side of a triangle is equal to the sum of the squares on the other 2 sides then the triangle is right.

square on longest side # = 29^2 = 841#

sum of squares on other 2 sides # = 20^2 + 21^2 = 841 #

This means that the triangle is right , with hypotenuse of 29.

Also the set 20,21,29 satisfy the Pythagorean Theorem
