Question 253145
An equilateral triangle is a triangle with sides of equal length. This means that the angles are of the same measure. Since there are 3 angles, and they add up to 180 degrees, this means that each angle is 60 degrees (since 60+60+60=3*60=180 degrees). Since each angle is 60 degrees, none of these angles are 90 degrees, which is a requirement to be a right triangle.



On the other hand, it is very possible to have an isosceles triangle that is also a right triangle. Just draw a triangle with two equal sides and a right angle.
