𝐺𝑖𝑣𝑒𝑛 ∆ABC~ ∆DEF, if ⦟A = 45° and ⦟E = 35° then ⦟B =?
- A45°
- B35°
- C25°
- D40°

Answer
$35^{\circ}$
In $\triangle \mathrm{ABC}$ and $\triangle \mathrm{DEF}$,
$\triangle \mathrm{ABC} \sim \triangle \mathrm{DEF}$...(Given)
$\therefore \angle B \cong \angle \mathrm{E}$ ...(Corresponding angles of similar triangles)
But $\angle \mathrm{E}=35^{\circ}$...(Given)
$\therefore \angle B=35^{\circ} \text {. }$
