Question

Construct a right angled triangle PQR in which angle P=90 degree QR = 7cm PQ = 3cm

Answer 1

$\dashrightarrow$ Steps :-

• First, draw a line segment QR of 7 cm.
• Next, take a protractor and keep it's mid-point on the point Q and draw a ray measuring 90°.
• Then, take a cómpass and measure it as 3 cm and keep it's tip on the point Q and draw an arc on the ray.
• Then, take pencil and ruler and join the point R to the arc drawn.
• Finally, the triangle is constructed.

$\dashrightarrow$ Instruments used :-

• Compàss :- Compàss is used to draw the arc on the ray drawn. Here, it's used to draw the arc on the ray drawn measuring 90°.
• Protractor :- Protractor is used to measure the angles, so that the angle's measurement is accurate.
