Question

construct a. ∆ABC in which BC =4.5 angle B =45° and AB-AC=2.5​

Answer 1

Step-by-step explanation:

We are given BC = 4.5 cm, ∠B = 450 and AB - AC = 2.5 cm Steps of Construction : (i) Draw a ray BX and cut off a line segment BC = 4.5 cm from it. (ii) Construct ∠XBY = 450 (iii) Cut off a line segment BC = 2.5 m from BY. (iv) Join AC. (v) Draw perpendicular bisector of CD cutting BY at a point A. (vi) Join AC. So, ΔABC is the required triangleRead more on Sarthaks.com - https://www.sarthaks.com/71726/construct-a-triangle-abc-is-which-bc-4-5-cm-b-450-and-ab-ac-2-5-cm
