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 Δ ABC, ∠B = ∠C . Then value of x is
16
12
8
4
If ∠P = ∠R and PQ is more than 5 cm but less than 6 cm. Length of QR is
4.8 cm
5.7 cm
6.5 cm
6 cm
If ∠A = 60o, ∠B = 80o and ∠C = 40o, then the longer side is:
AB
BC
AC
AD
In fig: AB = AC and DB = DC , then ∠ABD : ∠ACD =
1 : 1
1 : 2
2 : 1
2 : 2
The measure of each exterior angle of an equilateral triangle is :
60o
80o
120o
140o
In ΔABC , AB = AC and ∠B is more than 30o, but less than 45o. Then ∠C cannot be
33o
37o
41o
30o
