Question

the lengths of the sides of some Triangles are given below which of them are right angled a = 9 cm , b = 12 cm and c = 16 cm

Answer 1

the opposite angle of side "c"is right angle becoz the opposite side of the right angle is longer in triangle..........
but in this given sides 9cm,12cm and 16cm the right angle triangle are not formed
if you have any doubt....
you put their sides on the Pythagoras formula....than you understand your question is incorrect
I hope it's help you.....

Answer 2

Answer:

not right angle triangle.

Step-by-step explanation:

${a }^{2} + {b}^{2} = {c}^{2}$

${a}^{2} + {b }^{2} = {9}^{2} + {12}^{2}$

$81 + 144$

$\sqrt{225}$

$\sqrt{15 \times 15}$

$15cm$

Now,15 cm is not equal to c ,i.e.16 cm.

Ans)It is not a right angle triangle.
