CBSE Class 10 Maths (Standard) 2017 · Paper 30/2 · Question 23

Constructions (old syllabus) 4 marks Medium

Construct a triangle

A B C

with side

B C = 7

cm,

∠ B = 4 5^{\circ}

∠ A = 10 5^{\circ}

. Then construct another triangle whose sides are

\frac{3}{4}

times the corresponding sides of

△ A B C

Answer

△ A B C

has

∠ C = 3 0^{\circ}

and is drawn from

B C = 7

cm with the

4 5^{\circ}

and

3 0^{\circ}

base angles; the smaller triangle

A^{'} B C^{'}

is obtained by the 4-division parallel method so that each side is

\frac{3}{4}

of the corresponding side of

△ A B C
