Question

the sides of a triangle are 29cm,21 cm and 20 m.show that it is a right angled triangle

Answer 1

therefore by using pythagoras theorem
we can prove that it is right angle triangle...

Answer 2

Step-by-step explanation:

longest side = hypotenuse

= 29 cm

According to Pythagoras theorem

${hypotenuse}^{2} = {side }^{2} + {side}^{2}$

${29}^{2} = {21}^{2} + {20}^{2}$

841 = 441 + 400

841 = 841

therefore it is a right angled triangle
