The three angles inside any triangle always add up to 180 degrees.If one of them is 90 degrees, then the triangle is a right triangle.
No, a right angled triangle needs an angle that is 90 degrees. Here, all the angles don't even make up 180 degrees.
A triangle only has three sides. If you put three sticks together, you can make a triangle. If you had four sticks, you cannot make a triangle. That is why only three sticks are needed.
3, 5, 5 does not make a right angle triangle but they can make an isosceles triangle Correct. Try 3,4,5. That will be a right triangle. 3x3 plus 4x4 = 5x5

No. If 0.3 and 0.4 are the legs of a right triangle, then the third side has to be 0.5 .

No because the dimensions given do not comply with Pythagoras' theorem for a right angle triangle
A triangle cannot have more than one right angle, which measures 90o. The sum of all three angles in a triangle must equal 180o.
No, a right angled triangle needs an angle that is 90 degrees. Here, all the angles don't even make up 180 degrees.
By Pythagoras's theorem, to make a right angled triangle, 142 + 152 should be 212 But 142 + 152 = 196 + 225 = 421 whereas 212 = 441 So these three sides cannot make a right angled triangle.
