In triangle ABC, angle a = 2, angle B. when angle c =? It is an isosceles triangle Such as the title
An isosceles triangle is formed when the angle c equals 45 or 72 degrees
Because if it's an isosceles triangle, angle c is equal to angle a or angle B
Let angle B be x, then angle a be 2x, and angle c be X or 2x
According to the angle of the triangle and 180 degrees
X + 2x + x = 180 or x + 2x + 2x = 180
Calculate x = 45 degrees or x = 36 degrees
So the angle c is 45 degrees or 72 degrees
