Classify the following triangle. Check all that apply. I A. Obtuse
B. Acute
C. Scalene
D. slught
E. Isosceles
F. Equilateral

B. Acute and F. Equilateral

Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.

In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.

Hope this helps!

i dont know
