Question

Is the triangle whose sides are 17cm,15cm,and 8cm long right angled

Answer 1

To prove whether it is a right angle triangle , let us assume that it is a right angle triangle then , it must satisfy

PYTHAGORAS THEOREM

${17}^{2} = 289 \\ {15}^{2} + {8}^{2} = 225 + 64 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 289$

Since , L.H.S = R.H.S

Since , L.H.S = R.H.S Hence , it is a right angle triangle.
