Question

Question 8
If in two right triangles, one of the acute angles of one triangle is equal to an acute of the other triangle. Can you say that two triangles will be similar? Why?

Answer 1

True
Let two right angled triangles be $\Delta ABCand\Delta PQR$


In which $\angle A=\angle P={90}^{\circ }$
And $\angle B=\angle Q=acuteangle$
Then, by AAA similarity criterion, $\Delta ABC\sim \Delta PQR$
