Question

5.Construct an isosceles triangle whose base is 6cm and altitude is 4cm.Then construct another triangle whose sides are (3)/(4) times the corresponding sides of the isosceles triangle.​

Answer 1

Draw a line segment BC = 6 cm. 2. Draw a perpendicular bisector of BC which intersects the line BC at Q. 3. Mark A on the line such that OA = 4 cm. 4. Join A to B and C. 5. Draw a ray BX making an acute angle with BC. 6. Mark four points B1,B2,B3, and B4 on the ray BX. such that BB1 = B1B2 = B2B3 = B3B4. 7. Join B4C. Draw a line parallel to B4C through B3 intersecting line segment AB at A'. Hence ΔA'BC' is the required triangle.Read more on Sarthaks.com - https://www.sarthaks.com/176510/construct-an-isosceles-triangle-whose-base-is-6-cm-and-altitude-4-cm
