A : Two similar triangles are congruent.

B : Two congruent triangles are similar, then :

1. A is true, B is false

2. A is false, B is true

3. A is false, B is false

4. A is true, B is true

Triangles ABC and RSP are similar to each other, the corresponding sides of the two triangles are :

1. AB and RS

2. BC and RP

3. AC and SP

4. AB and RP

Triangles ABC and PQR are similar to each other, then :

1. $\dfrac{\text{Ar.(△ABC)}}{\text{Ar.(△PQR)}} = \dfrac{BC^2}{PQ^2}$

2. $\dfrac{AB^2}{PQ^2} = \dfrac{AC^2}{PR^2}$

3. $\dfrac{\text{Ar.(△BAC)}}{\text{Ar.(△QPR)}} \ne \dfrac{AB^2}{QP^2}$

4. $\dfrac{AC^2}{PR^2} = \dfrac{BC^2}{PQ^2}$

In the given figure, EF is parallel to BC. If area of triangle ABC is 576 cm², the area of triangle AEF is :

1. 128 cm²

2. 288 cm²

3. 256 cm²

4. 768 cm²
