3.)write a few sentences explaining how will you know wether a triangle is a right triangle if you know the three sides

i can answer only #2 ques.s

if the right triangle measures 30 deg.-60deg -90deg
double the shortest side to get the hypotenuse
multiply the shortest side by √3 to get the longer side

if the right triangle measures 45-45-90
multiply the one side by √2 to get the hypotenuse

a^ + b^2 = c^2
a^2=c^2-b^2
