Question

5 cm, 12 cm and 13 cm can be sides of a right-angled triangle. True/False?

• A. True
• B. False

Answer 1

The correct option is A True

$5^2=25$

${12}^2=144$

${13}^2=169$

$\therefore 25+144=169$

The sum of squares of two sides of a triangle is equal to the square of the third side, then that triangle will be a right-angled triangle.

5 cm, 12 cm and 13 cm will form a right-angled triangle.
