Question

construct a triangle PQR in which PQ =7 cm, P =60° and Q =90°​

Answer 1

➤ Correct Question :-

Construct a ∆PQR in which PQ = 7 cm, ∠P = 60° and ∠Q = 90°.

$\:$

$\dashrightarrow$ Steps :-

• First, draw a line segment PQ of 7 cm.
• Next, take a protractor and keep it's mid-point on the point P and draw a ray measuring 60°.
• Again, take a protractor and keep it's mid-point on the point Q and draw a ray measuring 90°.
• Join both the rays at a point. If they don't meet, extend the rays. The point where both the rays meets is named as point R.
• Finally, the triangle is constructed.

$\:$

$\dashrightarrow$ Instruments used :-

• Ruler :- The ruler is used to draw the line segments of accurate measurements and also the drawn lines should be straight.
• Protractor :- The protractor is used to draw the rays of accurate measurements of degrees. It's also used to measure the angles given.

Answer 2

❍ Correct Question :

$~$

• Construct a ∆PQR in which PQ = 7cm , $\bf\angle$P = 60° and $\bf\angle$Q = 90°.

$~$

$\large\bf\mapsto$ $\large{\bf\underline{Steps}}$:

• First , draw a line segment PQ of 7cm.
• Next , take a protractor and keep it's mid - point on the point P and draw a ray measuring 60°.
• Again , take a protractor and keep It's mid - point on the point Q and draw a ray measuring 90°.
• Join both the rays at a point. If they don't meet , extend the rays. The point where both the rays meets is named as point R.
• Finally , the triangle is constructed.
