Question

write the relation between the length of three sides of a right angled triangle. If the lengths of hypotenuse and base of right angled triangle are 5 cm.and 3 cm . respectively them then find the length of the perpendicular of the triangles .​

Answer 1

Answer:

3cm

Step-by-step explanation:

The relation between the lengths of the 3 sides of a right-angled triangle is given by Pythagoras' Theorem.

If a, b and c are the lengths of the 3 sides of a right triangle, c being the length of the hypotenuse,

$a^{2} +b^{2} =c^{2}$

c = 5cm, b=cm

$a^{2} + 3^{2} =5^{2}$

$a^{2} = 25-16$

$a^{2}=9$

a=3cm
