A triangle has sides with lengths of 20 millimeters, 24 millimeters, and 29 millimeters. Is it a right triangle?
1 Answer
No
Explanation:
#{(a = "20 mm"), (b= "24 mm"), (c= "29 mm") :}#
Use the Pythagorean Theorem:
#a^2 + b^2 = c^2#
Plug in the values
#20^2 + 24^2 = 29^2#
#400+576 != 841#
because
#400+576 = 976#
Thus, it is not a right triangle.
