Answer:

Acute

Step-by-step explanation:

Due to the fact that all the angles of an equilateral triangle have a measure of 60 degrees, the triangle must be acute as the measure of all acute angles are less than 180 degrees.

Answer:

Option B

Step-by-step explanation:

All equilateral triangles are "acute triangles" or option B. Acute triangles have degrees that are less than the degree of a right triangle which is 90 degrees. In this case all equilateral triangles have the sum of 60 degrees, which is less than the degree of a right triangle which means it is indeed a acute angle. It's not option D because obtuse triangles are triangles with angles that are more than 90 degrees, it's also not option C because each side of a scalene triangle is of different length in terms of degrees.

Hope this helps.
