Question

construct the following triangles the length of whose sides. are. given. construct a. triangle pQR whereQR=6.5cm PR=7.8Cm. and ∆R=4.5°
​

Answer 1

➤ Correct Question :-

Construct a triangle PQR, where QR=6.5 cm, PR=7.8 cm and ∠R=45°.

$\dashrightarrow$ Steps :-

• First, draw a line segment PR of 7.8 cm.
• Next, take a protractor and keep it's mid-point on the point R and draw a ray measuring 45°.
• Then, take a cómpass and measure it as 6.5 cm and keep it's tip on the point R and draw an arc on the ray.
• Now, join the point P where the ray and the arc meets. Name it as point Q.
• Finally, the triangle is constructed.

$\dashrightarrow$ Instruments used :-

• Ruler :- The ruler is used to draw the line segments of accurate measurements as per to the question. Also, the drawn lines should be straight.
• Protractor :- The protractor is used to draw the ray of accurate degrees. It's also used to measure the angles.
• Cómpàss :- The cómpàss is used to draw an arc on the ray drawn by taking the measurements.
