WebMar 19, 2024 · DE is parallel to BC . AE = 4 cm. AD = 3 cm. AC = 10 cm . Concept Used: AAA' similarity rule. If three angles of two triangles are equal then corresponding sides of similar triangles are proportional. Calculation: If DE is parallel to BC . ∠A = ∠A (Common) ∠ADE = ∠ABC (corresponding angles of parallel sides are equal) WebAnswer: Given, in ABC, DE∥BC. ∴ AD/DB = AE/EC (Using Basic proportionality theorem) ⇒1.5/3 = 1/EC. ⇒EC = 3/1.5. EC = 3×10/15 = 2 cm. Hence, EC = 2 cm. herdy online shop https://djbazz.net
