an are We know, equilateral triangle is a triangle in which all three sides equal. and also know that equilateral triangle is also equiangular, ie all three internal angles are equal. an equilateral triangle since it has three equal whose length A ABC is (2 12 sides 60° is 12 060° B 12 so, LA = LB=LC Since, LAT LB the = 180° LA+CA TLA = 180° 32A = 180° CA = 3 600 -> CA LA=LC = 60° LA=LB = 60° and Therefore, we get, LC= 60° LA 60°, LB = 60°, is answer Hence, own required 0 A = 60 B = 0 60
