In a $\triangle ABC$, $BC=AB$ and $\angle B={ 80 }^{ 0 }$. Then $\angle A$ is equal to?
The area of two similar triangles $\displaystyle \Delta ABC$ and $\displaystyle \Delta DEF$ are 144 $\displaystyle cm^{2}$ and 81 $\displaystyle cm^{2}$ respectively If the longest side of larger $\displaystyle \Delta ABC$ be 36 cm then the longest side of the smaller triangle $\displaystyle \Delta DEF$ is
The perimeters of two similar triangles are $25\;cm$ and $15\;cm$ respectively. If one side of first triangle is $9\;cm$, then the corresponding side of the other triangle is
If area $(\Delta ABC)=36 cm^2, area (\Delta DEF)=64 cm^2$ and $DE=6.4 cm$. Find AB if $\Delta ABC\sim \Delta DEF$
If the areas of two similar triangles are equal then the triangles :
Sides of two similar triangles are in the ratio of $5 : 11$ then ratio of their areas is
Sides of two similar triangles are in the ratio of $4 : 9$ then area of these triangles are in the ratio
Similarity is represented by :
When the ratios of the lengths of their corresponding sides are equal, then the two figures are:
Two triangles are $ABC$ and $PQR$ are similar, then symbolically it is represented as:
