Points O, A and C are lined up. The points O, B and D are lined up. (BA) and (BD) are perpendicular [OD] We provide the following: OA = 6 cm, 4.8 cm and OB = OC = 10 cm 1) Justify the triangle OCD is an enlargement of the rectangle OAB (I did a) Determine the number k such that: k OD = OB 2) Calculate the length of OD (I FOUND 8 cm, is what is right) 3) Calculate the? length AB and DC (how it's done?) 4) Let P be the perimeter of the triangle OAB and P 'that checks to see if the triangle ODC: P' = k * P (I do not understand at all) Hello thank you to explain to me how solve this exercise Laura.
Post by canto canto the king of the king you make a typo in your NONC ((CD) perpendicular (OD) and not (BD)). except for 2. it is right. For 3. I remind you that you speak your NONC perpendicular lines (big clue)
Post by ASK13 ASK13 And I have another year the figure is against CONSIDERED why: - the points R, S and E are lined up; - The points R, F and T are lined up; - Straight (EF) and (ST) are parallles. We denote by k the number k = dfini RE / RS Let P be the perimeter of the triangle REF and P 'of the triangle RST. Dmontrer that: P '= P kx How do we do to calculate a thing or there as letters?
Post by canto canto the king the king not P '= RS + ST + RT (until the it's good) P = RE + EF + RF after your NONC RE = k * RS therefore by Thals (I'll let you care to do so), we show that RF = k * RT and EF = k * ST. remplaant in the expression of P is obtained: P = k * RS * RT + k + k * k * T = P '
