Question Analysis:
This question tests fundamental properties of equilateral triangles, including angle relationships and special segment properties.

Key Concept Explanation:
An equilateral triangle has equal sides and equal angles.
Special segments (medians, altitudes, perpendicular bisectors, and angle bisectors) coincide in an equilateral triangle.

Step-by-Step Solution:
A) Correct – All angles in an equilateral triangle are always 60°.
B) Correct – In an equilateral triangle, the perpendicular bisectors, medians, and angle bisectors are the same.
C) Incorrect – The sum of interior angles in any triangle is always 180°, not 3...
