Question

Which of the following will form a right angled triangle, given that the two angles are:

• A. ${24}^o,{66}^o$
• B. ${36}^o,{64}^o$
• C. ${62}^o,{48}^o$
• D. ${68}^o,{32}^o$

Answer 1

Answer: (A)

${24}^o,{66}^o$

We know that the sum of angles of a triangle $={180}^o$

And one of the angles is of ${90}^o$ in right angled triangle

Then sum of other two angle is $180-90={90}^o$

(A)$24+66={90}^0$

(B)$36+64={100}^0$

(C)$62+48={110}^0$

(D)$68+32={120}^0$

Hence, only option A will form a right angled triangle.
