1.	(1) In the adjoining figure, AP 2 units, AQ-3 units, PB 6 units, QC-9 units,Show that BC- 4PQ
Answer» since PQ intersects the sides AB and AC in equal ratios. therefore PQ is parallel to BC. now the triangles APQ and ABC are similar triangles. therefore the ratios of the corresponding sides are equal.

Answer»

since PQ intersects the sides AB and AC in equal ratios.

therefore PQ is parallel to BC.

now the triangles APQ and ABC are similar triangles.

therefore the ratios of the corresponding sides are equal.
