Question

which of the following can be sided of right triangle?
a) 5cm ,12cm ,13cm
b)5cm ,10cm,15cm
c)2cm ,3cm,4cm
d)8cm ,12cm,15cm​

Answer 1

Step-by-step explanation:

a) AC² = AB² + BC²

= 13² = 5² + 12²

= 169 = 25 + 144

= 169 = 169

It can form a right angled triangle

b) AC² = AB² + BC²

= 15² = 5² + 10²

= 225 = 25 + 100

= 225 = 125

It cannot form a right angled triangle.

c) AC² = AB² + BC²

= 4² = 2² + 3²

= 16 = 4 + 9

= 16 = 13

It cannot form a right angled triangle.

d) AC² = AB² + BC²

= 15² = 8² + 12²

= 225 = 64 + 144

= 225 = 208

It cannot form a right angled triangle
