In an isosceles triangle, one of the medians is perpendicular to the opposite side of that triangle. In an equilateral triangle, all three medians are perpendicular to the sides of that triangle.
Adjacent sides are perpendicular. Opposite sides are parallel.
According to the Pythagorean theorem, the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides or, c^2 = a^2 + b^2. Since there is no single value where a = b= c, a right triangle cannot have all equal sides.
There are no numbers on that list that could be the sides of a right triangle. Oh, all right. The following is the answer:
If no two sides of a triangle have the same length, then the figure is called a "scalene" triangle. Some (but not all) scalene triangles are also right triangles.
all the sides
right angled triangle does not have all equal sides

Two of the three lines in a right triangle are perpendicular. Perpendicular lines meet at a 90 degree angle (also called a right angle). All right angle triangles have one right angle.

It has 2 equal sides of right triangle.
A square has four perpendicular sides.
A right triangle.
A triangle with a right angle and different lengths for sides is a right, scalene triangle.
It is the right angle triangle which has 3 sides whereas all quadrilaterals have 4 sides.
In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
