cho hình thang ABCD có AB=3cm, BC= 10cm, CD=12cm, AD= 5cm, BD= 6cm …
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 ... WebGiven: In a parallelogram ABCD, AB is the base.
