Pythagorean triple
A hypotenuse.
The figures given in the question cannot be a triangle, leave alone a right angled triangle.
An acute angled triangle, right angled triangle or obtuse angled triangle.
No. There can be no isosceles right angled triangle with all three sides being rational numbers.
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
acute angled triangle,right angled triangle,obtuse angled triangle,isosceles triangle,equilateral triangle, scalene triangle
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.
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.
The right-angled triangle.
An obtuse angled triangle is wider than a right angled triangle. It has 180 degree angles.
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
right angled triangle does not have all equal sides
