Question 1
Is the triangle with sides 25cm, 5cm and 24cm a right triangle? Give reason for your answer.

Answer 1

False, the triangle with sides 25cm, 5cm and 24cm is not a right triangle.
Let a = 25cm, b = 5cm and c =24 cm
Now, $b^2+c^2=(5{)}^2+(24{)}^2$
$=25+576=601\ne (25{)}^2$
Hence, the given sides do not make a right triangle because it does not satisfy the property of Pythagoras theorem.
