E) Use the Pythagorean Theorem to find out if these are right triangles.
Justify your answers.
a)3cm 4cm 5cm
b)6.4m 5.6m 2.5m
c) 9.6km 12.8km 16.0 km

This is neha to help you

before we begin  the formula of pythagoras thereom is

hypotenuse²= base²+altitude²

a) 3cm,4cm,5cm

in this the hypotenuse is 5cm because in this set the larger number will always be the hypotenuse

you can take the base and altitude the way you like but hypotenuse can taken by selecting the largest number from the set given to you

by applying the formula

hypotenuse = 5cm

base = 3cm

altitude = 4cm

hypotenuse²= base²+altitude²

(5)²=(3)²+(4)²

25=9+16

25=25

b) 6.4m, 5.6m,2.5m

hypotenuse= 6.4m

base= 5.6m

altitude = 2.5m

hypotenuse²= base²+altitude²

(6.4)²=(5.6)²+(2.5)²

40.96= 31.36+6.25

40.96= 37.61

c) 9.6km, 12.8km,16.0km

hypotenuse= 16.0km

base=12.8km

altitude=9.6km

hypotenuse²= base²+altitude²

(16.0)²= (12.8)²+ (9.6)²

256= 163.84+92.16

256=256
