Yes.
3 sides on a right triangle (on any triangle)+ two squares3 (triangle)+ 4 (one square)+ 4 (one square)-----------------------11i'm sorry if this is wrong and i misread the question
then the triangle is not a right trangle and has angles that are not 90 degrees.
Sometimes as in a square, rectangle or a right angle triangle
because the triangle is have a 3 sides and the square have a 4 sides
no... because a triangle has 3 sides and a square has 4 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.
Square the two smaller sides and add them together. Take the square root of the answer. If that is the same as the third side then you have a right angled triangle and if not, then you have not.
then the triangle is not a right trangle and has angles that are not 90 degrees.
An Isosceles right triangle. If the length of either of the two sides is N then the hypotenuse is N times the square root of 2. an isosceles right triangle can not be an equilateral triangle since the hypotenuse can not be the same size as the other two sides..
If you have a triangle then one of the sides cannot be perpendicular to the other two. It is true for a square but it is impossible with a triangle. Definition of perpendicular: Being at right angles to the horizontal; vertical.
(The square of the shortest one) + (the square of the medium one) = (the square of the longest one)
No because a square fas 4 sides whereas a triangle has 3 sides
Sometimes as in a square, rectangle or a right angle 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.
If it is a right angled triangle it will conform to Pythagoras' Theorm: The square of the hypotenuse = the sum of the squares on the other two sides. The hypotenuse would be the longest side, so add the two shorter sides squared together and if this equals the longest side squared then the triangle is a right angle triangle.
because the triangle is have a 3 sides and the square have a 4 sides
