( include least 3 steps of workings)

Answer 1

Answer:

yes , the triangle ABC is right angled

Step-by-step explanation:

hypotenuse = 17 cm

base = 8 cm.

perpendicular = 15 cm

By using Pythagoras theorem =

${h}^{2} = {p}^{2} + {b}^{2}$

${17}^{2} = {15}^{2} + {8}^{2}$

$289 = 225 + 64$

$289 = 289$

Hence proved that triangle ABC is right angled
