Triangle 1 is a right triangle

Triangle 2 is not a right triangle

Triangle 3 is a right triangle

Step-by-step explanation:

Triangle 1: 30^2 + 40^2 = 50^2

                 900  +  1600 =  2500

                             2500 =  2500

Triangle 2: 4^2 + 4^2 = 16^2

                     16 + 16 = 256

                           32 = 256

Triangle 3: 48^2 + 55^2 = 73^2

                 2304 + 3025 = 5329

                             5329 = 5329

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
