Answer 1

Solution

Classify the triangle to acute, obtuse, right or not triangle;

$21,28,35$

Using the pythagoras theorem to verify

Hypotenuse = 35

Opposite = 21

Adjacent = 28

$\begin{gathered} Hyp^2=opp^2+adj^2 \\ 35^2=28^2+21^2 \\ 1225=784+441 \\ 1225=1225 \end{gathered}$

There is equality in the equation ,

Hence pythagoras theorem is prooved

Therefore it is a right angle triangle

Final answer is Option C
