A 5*5 grid offers squares of sides 4, 3, 2 and 1 - as follows:
1 of 4*4
4 of 3*3
9 of 2*2
16 of 1*1
That's true.
In a right triangle, the square of one side must be the sum of the squares of the other two sides.
So it's impossible for all three sides to be equal.
2892 = 289 x 289 = 83,521
False.
The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
The shortest side
In order to find length BC the length of AC or length of the hypotenuse must be given
70
10 cm
