, and given DE = 4 cm, AB = 10 cm, and the side in ABC (say AC) is 6 cm: \[ \frac{4}{10} = \frac{DF}{6} \] Cross-multiplied: \[ DF = \frac{4}{10} \times 6 = 0.4 \times 6 = 2.4\, \text{cm} \] Answer: DF = 2.4 cm Practical Applications of Similar Right Tria
roperties helps in identifying and proving similarity: Corresponding angles are equal. Corresponding sides are in proportion, i.e., their ratios are equal. The ratio of the areas of two similar polygons is the square of the ratio of their corresponding s

= 60°, and ∠F = 70°. Are the triangles similar? Explain. Solution: Since all corresponding angles are equal: ∠A ≅ ∠D (50°) ∠B ≅ ∠E (60°) ∠C ≅ ∠F (70°) By the AA criterion, ΔABC ~ ΔDEF. Conclusion: The triangles are similar because they have equal corresponding angles. Example 2: Using SSS t
