ՏO Tᕼᗴ ᑫᑌᗴՏTIOᑎ ᗯᗩՏ - Show that the angles of an equilateral triangle are 60° each. Solution: Let ABC be an equilateral triangle Here, BC = AC = AB (Since the length of all sides is same) ⇒ A = B =C (Sides opposite to the equal angles are equal.) Also, we know that A+B+C = 180° ⇒ 3A = 180° ⇒ A = 60° ∴ A = B = C = 60° So, the angles of an equilateral triangle are always 60° each.
