Question

Tell whether the triangle with the given sides length is a right angled triangle.

$1in,2.4in,2.6in$

Answer 1

Hint: For a triangle to be a right angled triangle

${(Longestside)}^2=$Sum of squares of other two sides

Step 1: Longest side = $2.6$ in

Other two sides = $1$ in and $2.4$ in

Step 2: ${(2.6)}^2={(2.4)}^2+{\left(1\right)}^2$

Step 3

$$\begin{gathered} 6.76=0.96+1 \\ 6.76\ne 1.96 \end{gathered}$$

Final Answer: Given triangle is a not right angled triangle.
