In an isosceles triangle, the vertex angle is twice either base angle.

1.	In an isosceles triangle, the vertex angle is twice either base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees). Set up an equation.
Answer» ANSWER: LET base angle = B so VERTEX angle = 2b sum of angles = 180 degrees so, 2b + b + b= 180 degrees 4B = 180 degrees Here is ur answer Hope it helps..

Answer»

LET base angle = B

so VERTEX angle = 2b

sum of angles = 180 degrees

so,

2b + b + b= 180 degrees

4B = 180 degrees

Here is ur answer
