no.
A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees.
A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.

No.
No but it is possible for it to be an isosceles triangle with angles of 45, 45 and 90 degrees
Yes and it will have 3 equal sides
no...beacuse a parallelogram has to have parallel sides....a triangle can never have parallel sides
No, never. There's more than one way to get at it: -- The angles of an equilateral triangle are all equal. Since the interior angles of any triangle always add up to 180 degrees, the angles of an equilateral triangle are each 60 degrees. There's no right angle. -- A right triangle is a triangle with an interior right angle. An equilateral triangle has three equal angles. If it were a right triangle, each angle would be a right angle. Then: -- the three interior angles would add up to 270 degrees, which is impossible in a triangle; and -- two sides would be parallel to each other, they would never meet, and there could be no triangle. -- The sides of a right triangle satisfy the Pythagorean equation: A2 + B2 = C2. If all three sides were equal, then you'd have (two times the square of a number) equal to (the square of the same number), which isn't possible. -- Remember that the 'hypotenuse' of a right triangle is the longest side. But an equilateral triangle can't have a 'longest' side.NOA right triangle always has a 90 degree angle and an equilateral triangle always has three 60 degree angles, so no.
