Mensuration Practice Test 2

Question : 4 of 40

Marks: +1, -0

The ratio of the areas of two isosceles triangles having the same vertical angle (i.e., angle between equal sides) is 1 : 4. The ratio of their heights is:

1 : 4
2 : 5
1 : 2
3 : 4

Validate

Solution:

Area of triangle =

1/2 bh

A =

4(1/2 bh)

1/2 bh

1/2

(2b) (2h)
[Since both base and height increase in the same proportion.]
So, both the heights will be in the ratio of 1 : 2.
