Web26 aug. 2024 · Best answer Given: ∆ABC ∼ ∆DFE, As ∆ABC ∼ ∆DFE so, by the property of Corresponding angles of similar triangles, We have, ∠A = ∠D = 30° (Corresponding angles) ∠C = ∠E = 50° (Corresponding angles) We know that sum of angles of a triangle = 180° So, ∴ ∠B = ∠F = 180°- (30° + 50°) = 100° Also Given, AB = 5 cm, AC = 8 cm and DF = 7.5 … Web19 jan. 2024 · AB = 14. m∠F = 39°. Well the explanation here is simple. Since the given states that the two triangles, ΔABC and ΔDEF, are congruent, they must have congruent/corresponding parts. So AB is the same as DE which measures 14, so therefore AB must measure 14. The same explanation goes to m∠F, ∠C is congruent to ∠F so it …
Web19 okt. 2024 · In ΔDEF, the corresponding side of BC is EF and ΔABC ~ ΔDEF such that, EF = 8cm. With this information, we are asked to find out the perimeter of ΔDEF. We know that, Sum of all sides is equal to perimeter. In ∆ABC, we have; ⇒ Perimeter (∆ABC) = AB + BC + AC ⇒ Perimeter (∆ABC) = 9cm + 6cm + 7.5cm ⇒ Perimeter (∆ABC) = 22.5cm
