Fill in the Blanks: The greatest side of a right angled triangle is______

Fill in the Blanks: The difference between any two sides of a triangle is______ the third side.

The ratio between the circumradius and invadius of a right angled isosceles triangle is

In a right angle triangle, length of the hypotenuse is 6 cm more than its shortest side. The length of the other side is 3 cm less than the hypotenuse, then find the sides of right angle triangle.

Converse of Pythagoras theorem: In a triangle if the square of one side is equal to the sum of squares of the other two sides, then the angle opposite to the first side is a right angle and the triangle is a right angled triangle.

Without using the Pythagoras theorem, show that the points (4,4), (3, 5) and (-1, -1) are the vertices of a right angled triangle.

If the length of sides of right angled triangle are in A.P., then the sines of the acute angles are
