Question

Construct an isosceles triangle whose base is 7 cm and altitude 4cm and then construct another similar

Answer 1

Steps of Constructions :

1. Draw a line segment BC = 7cm.

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
