Answer:
✓3 cm
Step-by-step explanation:
make a right angle triangle with half base, an altitude and a hypotenuse by diving the equilateral triangle into 2 equal parts
Pythagoras theorem
hypotenuse² = altitude²+base²
hypo. = 2cm
base = 1cm (half of the total base of the triangle)
2²=altitude ²+ 1²
4-1=altitude²
3= altitude²
✓3cm = altitude
