Triangles Test ...

If ABC and DEF are similar triangles such that $$\displaystyle \angle A=47^{\circ}$$ and $$\displaystyle \angle B=83^{\circ}$$ then $$\displaystyle \angle F$$ is

In the given figure, $$DE\parallel BC$$, $$AD=2\:cm$$, $$DB=3\:cm$$ and $$AE=1.6\:cm$$. Then EC is equal to

In $$\triangle{ABC}$$, $$\angle{B}=90$$, $$AB=8\:cm$$ and $$BC=6\:cm$$. The length of the median BM is

Which one of the four hexagons is not similar to the other three?

The areas of two similar triangles are $$\displaystyle 9\ { cm }^{ 2 }$$ and $$\displaystyle 16\ { cm }^{ 2 }$$, respectively. The ratio of their corresponding heights is:

Two poles of heights 10 m and 15 m, stand on a plane ground. If the distance between their feet is 12 m, the distance between their tops is

Which one of the four pentagons is not similar to the other three?

When the ratios of the lengths of their corresponding sides are equal, then the two figures are:

A............ can never be made up of all odd numbers or two even numbers and one odd number.

The Pythagoras theorem , In the right triangle, the square of the hypotenuse is equal to the sum of other two sides. What are we proving here?
