Question

Construct a triangle PQR such that PQ=5.4cm, ZP= L 45º and ZQ= L 60°.

(Here L=angle)​

Answer 1

➤ Correct Question :-

Construct a triangle PQR such that,

PQ :- 5.4 cm

∠RPQ :- 45°

∠PQR :- 60°

$\dashrightarrow$ Steps :-

• First, draw a line segment PQ of 5.4 cm.
• Now, take a protractor and keep its mid-point on the point P and draw a ray measuring 45° (facing right side).
• Again take a protractor and keep its mid point on the point Q and draw a ray measuring 60° (facing left side).
• Join both the ray at the common point. The point where both the rays meet is called point R.

$\dashrightarrow$ Instruments used :-

• Ruler :- Ruler is used to draw the lines straight and to draw the lines of accurate measurements. The measurements of the lines should be correct.
• Protractor :- Protractor is used to measure the angles given. It's mainly used to measure the angles. Here it's used to draw the line segment of 45° and 60°.

More to know :-

• While constructing the triangle always draw the base, for which line has greatest measurement.
• Use ruler for accurate measurement and the construction should be as per to the question${.}$
