Question

Triangle ABC has the measures of10cm, 5 cm, hand 15cm. Is it a righttriangle?

Answer 1

according to the pythagorean theorem the square of the largest side must be equal to the addition of the other sides square

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

use the pythagorean theorem to prove

`\begin{gathered} 10^2+5^2=15^2 \\ 100+25=225 \\ 125\\e225 \end{gathered}`

the triangle is not a right triangle
