Question

determine if a triangle with sides of given length is a right triangle: 9,12,15 and 10,22,26.​

Answer 1

Answer:

9,12,15 = is a right angled triangle

10,22,26 = not a right angled triangle

Step-by-step explanation:

(hypotenuse)2 =(side)2+(side)2

(15)2 = (9)2 +(12)2

225 =225

therefore, this is a right angled triangle

similarly,

(26)2 = (22)2 + (10)2

676 = 484 + 100

676=/ 584

therefore, this is not a right angled triangle
