Exercise

In the given figure, if $\angle S=\angle R$, then which triangles are similar?

What is the ratio of the perimeter of these two triangles?

In the figure, $△XYZ~△LMN$ observe the figure and find the value of $XZ \mathrm{and} LM$.

Select the correct correspondence to describe the similarity between the given triangles.

In a $\Delta ABC\mathit{,}D$ and $E$ are points on the sides $AB$ and $AC$ respectively such that $DE \Vert BC$. If $AD=2.4 \mathrm{cm}, AE=3.2 \mathrm{cm},DE=2 \mathrm{cm}$ and $BC=5 \mathrm{cm},$ find $BD$ and $CE$

In triangles $\mathrm{PQR} \mathrm{and} \mathrm{TSM}$, $\angle \mathrm{P} = 55°, \angle \mathrm{Q} = 25°, \angle \mathrm{M} = 100°$, and $\angle \mathrm{S} = 25°$. Is $∆\mathrm{QPR} ~ ∆\mathrm{TSM}$? Why?

In the adjoining figure , find the length of $AD$ in terms of $b$ and $c.$

If $△PQR~△ABC, PQ=6 cm, AB=8 cm$ and perimeter of $△ABC$ is $36cm$, then perimeter of $△PQR$ is
