Joel wants to fence off a triangular portion of his yard for his chickens. The three pieces of fencing he haas to use are 8 feet

Sedaia [141]

No, it will not be able to make a right triangle.

Solution:

Given that,

Joel wants to fence off a triangular portion of his yard for his chickens.

The length of three peices of fencing are 8 feet , 15 feet and 20 feet

For making it a right triangle it must satisfy the "Pythagorus theorem"

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

For a right angled triangle with sides a, b, c

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

Given sides are:

a = 8 feet

b = 15 feet

c = 20 feet

Substituting the values in above formula

$20^2 = 8 ^2+15^2\\\\400 = 64 + 225\\\\400\neq 289$

Since the pythogoras formula is not satisfied, the given sides cannot form a right angled triangle

Thus , No, it will not be able to make a right triangle.
