The answer is never.

Never but an isosceles triangle can sometimes be a right angle triangle
No, an equilateral triangle always has 3 equal angles (each angle is 60°)
no, it is impossible an angle of an equilateral triangle is always 60 degrees it can't be 90 degree
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
An equilateral triangle is a shape with three sides of the same length, and the angle in between the sides is always 60o.
equilateral triangle
No, since an equilateral triangle has three congruent angles of 60 degrees, and a right triangle must have an angle of 90 degrees. However, a right triangle may be an isosceles triangle.
Each interior angle of an equilateral triangle measures 60 degrees
an equilateral triangle has 3 congruent sides and angle measures.
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
These are some characteristics of equilateral triangle:All the sides of an equilateral triangle are equalIn an equilateral triangle each angle is angle is 60 degree.With an equilateral triangle, the radius of the incircle is exactly half the radius of the circumcircle.
