Question

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

Answer 1

Answer:

In an isosceles triangle, the vertex angle is twice the base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees).

Step-by-step explanation:

Solution

Let the base angle =b

⇒vertex angle =2b

Sum of angles in a triangle =180  °

 ⇒b+b+2b=180

⇒b=45  °

Angles =(45  °  ,45  °

,90  °  )
