Question 7 of 10

8. Pick out the incorrect statement

Sides opposite to equal angles are equal in a triangle

If the altitude from one vertex of a triangle bisects the opposite side, then the triangle is isosceles

If the bisector of the vertical angle of the triangle bisects the base of the triangle, then the triangle is isosceles

All the altitudes of an isosceles triangle are equal
