Question

construct a triangle ABC with BC=6cm, angle B=35 and angle A= 45​

Answer 1

Answer:

Steps of Construction: Construct BC = 6 cm Construct ∠CBX = 30o From BX, cut the line segment BD which is equal to AB – AC = 3.5 cm Join the points CD Construct a perpendicular bisector of CD which meets BX at the point A In order to obtain the required triangle ABC join CA Justification: We know that A lies on CD which is the perpendicular bisector So we get AD = AC We know that BD = 3.5 cm It can be written as AB – AD = 3.5 cm So we get AB – AC = 3.5 cm Therefore, △ ABC is the required triangle.Read more on Sarthaks.com - https://www.sarthaks.com/728406/construct-a-abc-in-which-bc-6cm-b-30and-ab-ac-3-5cm-justify-your-construction
