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.
No.Examples:The right angled triangles {3, 4, 5} & {6, 8, 10} are similar;The right angled triangles {3, 4, 5} & {5, 12, 13} are just two right angled triangles.
A square is a right angled parallelogram with 4 right angles and all opposite sides parallel.
right angled triangle does not have all equal sides
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.
All triangles have 180o. A right-angled triangle has one right angle. A right angle is 90o.
A right-angled triangle is one which has, as one of the angles, an angle of exactly 90 degrees.
The longest side in a right angled triangle is called a hypotenuse.
