True, but a right triangle doesn't have to be isoceles.
In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles (namely, the angles opposite the congruent sides).
So it the side adjacent to the 90 degree angle are the same length you have an isoceles triangle.

No. A right angle can not be isosceles. Isosceles means two sides are equal and usually refers to a triangle or a trapezoid. It never, however refers to an angle.
If you draw a square and then draw one of the diagonals, you will divide the square into two isosceles right triangles. If the sides of the square are = 1 unit, the the diagonal will be
sqrt(2) units in length.

A right triangle can be isosceles if one angle is 90 and 2 sides are equal.

In a right angled isosceles triangle , sides are in ratio:-
1:1:â2 (â2 is the hypotenuse)
So it is true.

yes it can be possible, if only the other two angles are 45 degrees each. as long as two sides, or two angles r equal, it's an isosceles. so one of the angle can be 120 degrees n the other two r 30 degrees each.

this is only true if the angles are 90, 45, 45.

Yes, as long as two sides are of equal length, and two congruent angles.
