Constructions (old syllabus) 4 marks Medium

Write the steps of construction of constructing a triangle whose sides are of length

5

cm,

6

cm and

7

cm. Then write the steps of construction of another triangle whose sides are

\frac{3}{4}

of the corresponding sides of the former triangle.

Answer

Construct

△ A B C

with

B C = 5

A B = 7

C A = 6

cm; then divide a base ray

B X

into

4

equal parts, join

B_{4} C

, draw

B_{3} C^{'} ∥ B_{4} C

and

C^{'} A^{'} ∥ C A

. The triangle

A^{'} B C^{'}

has all sides

\frac{3}{4}

of the original.
