Answer 1

Step-by-step explanation:

To answer the question, we can use the Pythagoras theorem

`c^2=a^2+b^2`

For the first option

`\begin{gathered} 23^2+143^2\\e145^2 \\ \text{This is not }a\text{ right triangle} \end{gathered}`

For the second option

`\begin{gathered} 28^2+195^2=197^2 \\ \text{This is a right triangle} \end{gathered}`

For the Third option

`\begin{gathered} 135^2+140^2\\e175^2 \\ \text{This is not a right triangle} \end{gathered}`

For the fourth option

`\begin{gathered} 56^2+16^2\\e65^2 \\ \text{This is not a right triangle} \end{gathered}`
