Question

In an isoceles trangile the vetex angle in twice either base angle in degrees remember that the sum of angle of a tringke is 180 degrees​

Answer 1

Answer:

Sum of angles in a triangle= 180 degrees. There are 2 base angles and 1 vertex angle. So, 2b+b+b = 180 4b= 180

Answer 2

Answer:

Explanation:

An isosceles triangle has two sides of equal length. Likewise, the opposite angles of the sides are the same

So lets assume each angle be

x

and the bigger angle be

2

x

(since it is twice the base angle)

Now, we know that sum of the angles in a triangle is 180 degree

So,
