A right triangle can be an isosceles triangle, because the definition of an isosceles triangle is a triangle that has 2 sides equal to each other. A 45,45,90 degree triangle has 2 sides equal to each other, while the hypotenuse is different. It cannot be an equilateral triangle because of the formula a^2+b^2=c^2. With this formula, there is no possible way that: a, b, and c can all be equal to each other.
To recap: It can be an isosceles triangle, but not an equilateral one.
It can be scalene or isosceles but not equilateral.
An equilateral and right triangle are contradictory.
One more because an equilateral triangle has 3 equal sides whereas a right isosceles triangle has only 2 equal sides.
No. An obtuse triangle can be isosceles. It just can't be a right or equilateral triangle.
Never but an isosceles triangle can sometimes be a right angle triangle
It can be scalene or isosceles but not equilateral.
there is equilateral triangle, right triangle, isosceles triangle, obtuse triangle, acute triangle, scalene triangle and oblique triangle
No but it can be an isosceles triangle.
equilateral
In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle has TWO sides of equal length but and equilateral triangle has THREE sides of equal length.
Either an isosceles or a scalene triangle can have one right angle.

Any triangle that is not isosceles or equilateral. An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.
