If the bases of two triangles are situated on same line and other vertex of the two triangles are common, then the ratio of the areas of two triangles ______to the ratio of their bases.

Answer: equal

Explanation:

Area of Δ ABC / Area of ΔBCD={ ( 1 / 2 ) × AC × BC }/ { ( 1 / 2 ) × CD × BC }

=AC/CD

∴ Ratio of areas = ratio of bases
