WebDec 3, 2024 · ABCD is a parallelogram AB = 10 cm AD = 6cm. The bisector of ∠A meets DC at E. AE and BC produced meet at F. Since, AF bisects ∠A, We get, ∠BAE = ∠EAD … (1) ∠EAD = ∠EFB … (2) [Alternate angles] From equations (1) and (2), We get, ∠BAE = ∠EFB Since sides opposite to equal angles are equal, We get, BF = AB Here, AB = 10 cm So, BF = 10 cm WebApr 13, 2024 · Or BC = AD = 6 cm et BF = FC + FB = 4,4 + 8 = 12,4 cm. On a donc : 6 / 12,4 = BI / 8. ce qui donne BI = 3,06 cm. On peut donc placer I sur la droite (CD) à une distance de 3,06 cm de D. Le triangle CFI est bien l'image du triangle ABF par une homothétie de centre G et de rapport 0,5. En effet, on a : GA / GB = 5 / 8 = 0,625. FA / FB = 4,4 / 8 ...

We are given that parallelogram ABCD, side AB = 10 cm, and side BC = 15 cm. We know that the opposite sides are equal to each other, therefore, AB = 10 cm, = CD and side BC = 15 cm = AD Hence, AD=15cm, and CD= 10cm. Learn more about … fnf back alley blitz mod
