Questions  

The points A(2a,4a),B(2a,6a)  and C(2a+3a,5a)  (whena>0)  are vertices of

a
an obtuse angled triangle
b
an equilateral triangle
c
an isosceles obtuse angled triangle
d
a right angle triangle

detailed solution

Correct option is B

AB=(2a−2a)2+(4a−6a)2=2a BC=(2a+3a−2a)2+(5a−6a)2=(3a)2+a2=2a     and CA=(2a−2a−3a)2+(5a−4a)2=(3a)2+a2=2a Since AB=BC=CA,  the triangle is an equilateral.
