Question

Construct an isosceles triangle whose base is 7.5 cm and altitude is 3.5cm then another triangle where as side are 4/7 times the corresponding order of the isosceles triangle

Answer 1

Answer:

Step-by-step explanation:

Steps of construction :

1. Draw a line BC = 7.5 cm.

2. Draw a perpendicular bisector of BC which intersects the line BC at O.

3. Cut the line OA = 3.5 cm.

4. Join A to B and, A to C.

5. Draw a ray BX making an acute angle with BC.

6. Locate 7 points at equal distance among B1,B2,............, B7 on line segment BX.

7. Join B7C. Draw a parallel line through B4 to B7C intersecting line segment BC at C'.

8. Through C' draw a line parallel to AC intersecting line segment AB at A'.

9. Hence, ΔA'BC' is a required triangle
