WebIn the following figure, E is a point on side CB produced of an isosceles triangle ABC with AB = AC. If AD ⊥ BC and EF ⊥ AC, state whether ΔABD ~ ΔECF. Answer: Given, ABC is an isosceles triangle. ∴ AB = AC ⇒ ∠ABD = ∠ECF In ΔABD and ΔECF, ∠ADB = ∠EFC (Each 90°) ∠BAD = ∠CEF (Already proved) ∴ ΔABD ~ ΔECF (using AA similarity criterion) WebMay 10, 2024 · Question - In Fig. 6.40, E is a point on side CB produced of an isosceles triangle ABC with AB = AC.

WebDec 3, 2024 · Now, we have to prove that E is the mid-point AC. Therefore, ∆ABC and DE BC, We know that if a line drawn parallel to one side of triangle, intersects the other two sides in distinct points, then it divides the other two side in same ratio. So, AD/DB = AE/EC => DB/DB = AE/EC => 1 = AE/EC => AE = EC WebNCERT Solutions for Class 10 Maths exercise 6.3- Triangles defines the standards required to demonstrate the resemblance of triangles. some critical criteria or theorems for congruence of triangles in NCERT book Class 10 Maths chapter 6 exercise 6.3 are the Angle-Angle-Angle (AAA), Angle-Side-Angle (ASA), and Side-Side-Side (SSS). ezt code
