Which one of the following is not a measures of sides of a right angled triangle ---
a 43,5
b) 5.12.13 c)24, 25,7 d) 8,12 15
The ratio 3:4 Areas of these triangles are in​

Answer 1

Answer:

the Right-angled triangle square of the hypotenuse is equal to the sum of the square of the base and perpendicular and hypotenuse is the longest side of the triangle.

∴H

In option A

B=9 cm,H=15 cm,P=12cm

∴H=

9

2

+12

2

⇒H=

81+144

⇒H=

225

⇒H=15cm

Hence this is the side of Right angled triangle.

In option B

B=1 cm,H=

5

cm,P=2cm

∴H=

1

2

+2

2

⇒H=

1+4

⇒H=

5

Hence these are the side of Right angled triangle.

In option C

B=5 cm,H=9cm,P=7cm

∴H=

5

⇒H=

25+49

⇒H=

74

Here H



=9 then these are not the side of a right angled triangle
