Question

Could the triangle be classified as a right triangle?

Answer 1

as you recall from the pythagorean theorem, which applies only to right-triangles, c² = a² + b².

so, a = 6, b = 8, c = 9...... if that triangle is indeed a right triangle, then 9² = 6² + 8², let's check if that's true.

`\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=√(a^2+b^2) \qquad \begin{cases} c=\stackrel{hypotenuse}{9}\\ a=\stackrel{adjacent}{6}\\ b=\stackrel{opposite}{8}\\ \end{cases} \\\\\\ 9=√(6^2+8^2)\implies 9=√(36+64)\implies 9=√(100)\implies 9\\e 10~~\bigotimes~~nope`

Answer 2

yes , this is a right triangle as the angle on the top is of 90° (right angle)
