Use the Pythagorean Theorem: a^2 + b^2 = c^2 where c is the longest side (hypotenuse) of the right triangle.
So
a = 12
b = 12
(12)^2 + (12)^2 = c^2
144 + 144 = c^2
288 = c^2
*Take the square root of both sides
sqrt(288) = c
16.97056... = c
After rounding to the nearest foot, you find that c ~= 17ft

A triangle with 2 equal sides but no right angle?
a triangle with two sides the same length and no right angle
Is a right triangle an isosceles triangle?
It can be. If two of the sides of a right triangle are the same length then it is an isosceles triangle
What is the difference between an isosceles triangle and a right triangle?
In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle has TWO sides of equal length but and equilateral triangle has THREE sides of equal length.
Does a right-angled triangle have any equal sides?
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.

What is it when all the sides of a triangle are diffrant in length?
A right triangle.
What is a right scalent triangle?
A right scalent triangle is a triangle with a right angle and no sides equal in length.
What right triangle has legs of equal length?
It's not possible to have a right angle triangle with sides of equal length. The sides on a right angle triangle are always in the ratio 3:4:5.
A triangle with 2 equal sides but no right angle?
a triangle with two sides the same length and no right angle
Is a right triangle an isosceles triangle?

What triangle has all sides the same length and has a right angle?
equilateral right triangle
What is the name of A triangle with sides of no equal length?
A triangle with no right angle and sides of different lengths is a scalene triangle.
What is the length of the hypotenuse if the sides of the right triangle are 6 meters each?
The length of the hypotenuse if the sides of the right triangle are 6 meters each is: 8.485 meters.
Pythagoras determined that the length of any side of an is based on the length of its other two sides?
right triangle
What happens if a triangle is right-angled and has two equal length sides?
You have a proper right triangle with sides of {1 1 √2 } ■
