To see if it's a right triangle we need to determine if a²+b²=c²
([tex] \frac{3}{20} [/tex])² + ([tex] \frac{1}{5} [/tex])² = [tex] \frac{1}{4} [/tex]
[tex] \frac{9}{400} [/tex] + [tex] \frac{1}{25}[/tex] = [tex] \frac{1}{16} [/tex]
[tex] \frac{9}{400} [/tex] + [tex] \frac{16}{400} [/tex] = [tex] \frac{25}{400} [/tex]
[tex] \frac{25}{400} [/tex] = [tex] \frac{25}{400} [/tex]
So it is a right triangle
