It would help to know the definitions of acute and equilateral.
An acute triangle is one whose angles are all less than 90o.
An equilateral triangle is one whose sides are all the same, but that also means the angles will all be the same (60o)
So, every equilateral triangle will be acute.
Yes, a triangle can be both acute and equilateral.

RossYes, any equilateral triangle is also equiangular, meaning all three angles in the triangle have the same measure: 60 degrees (remember, the sum of the angles in a triangle equals 180). Therefore the equilateral triangle is also acute, meaning all three angles measure less than 90 degrees each.

Is it possible to draw a triangle that is both obtuse and equilateral?
No because an equilateral triangle has 3 equal acute angles of 60 degrees
Can an equilateral triangle be acute?
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
Are all equilateral triangles acute triangles?
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
How many line of symmetry does an acute triangle has?
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
How many acute angles in an equilateral triangle?
An equilateral triangle has all three angles equal and they must sum to 180 degrees. So 180 divided by 3 is 60 which is an acute angle. There are three acute angles in an equilateral triangle.
