Using the Pythagorean theorem: 20²+21² = 400+441 = 841 = 29²
So the hypotenuse is of length 29

Is A triangle with sides of lengths 12 15 and 20 a right triangle?
No. Pythagoras' theorem states that when the square of the hypotenuse is equal to the sum of the squares of the other two sides then it is a right-angled triangle. The hypotenuse is the longest side (opposite the supposed right angle). In this case the hypotenuse is 20. The square of 20 is 400. The other two sides are 12 and 15. The square of 12 is 144 and the square of 15 is 225. The sum is therefore 225 + 144 = 369, which is not equal to 400, therefore the triangle cannot be a right-angled triangle.
A right triangle has a hypotenuse of length 25 and a leg of length 15 What is the length of the other leg?
20 units
What is the length of BC in the right triangle below with legs of 12 and 16?
Using Pythagoras' theorem its hypotenuse will be 20
A right triangle has a hypotenuse of length 25 and a leg of length 20?
A right triangle has a hypotenuse of length 25 and a leg of length 20. Applying Pythagoras theorem , h sq .= b sq. + p sq. 25 X25 = 20 X 20 + sq.p. 625 -400= perpend sq. now.perpendicular = sqrt (225) =15 ( as no units are not given ).
One leg of a right triangle is 20 cm what is the hypotenuse?
the hypotonose of a triangle is the square root or one side squared plus the other side squared.
The length of the hypotenuse of a triangle is 20 what is the shorter leg?
You need to know something else to solve: either the long leg or the angle edit: if it is a right triangle you can use a theorem to figure out the other sides. the smallest side is a, the hypotenuse is 2a, the longer leg is a * sqrt (3) if the hypotenuse is 20, the smaller leg is 10.
