If the altitude from one vertex of a triangle bisects the opposite side, then the triangle is:
Equilateral
Isosceles
Scalene
Right Triangle
In an isosceles triangle , if the vertex angle is twice the sum of the base angles, then the angles of the triangle are:
120o, 30o , 30o
100o , 40o , 40o
100o, 50o , 30o
80o , 50o, 50o
In the given figure AB = AC = AD , ∠B = 23o and ∠D = 47o. Then ∠BCD =
24o
20o
110o
70o
In ΔABC , AB = AC and ∠B is more than 30o, but less than 45o. Then ∠C cannot be
33o
37o
41o
30o
In fig: AB = AC and DB = DC , then ∠ABD : ∠ACD =
1 : 1
1 : 2
2 : 1
2 : 2
