Question

Construct ΔPQR such that ∠R = 100°, QR = RP = 5.4 cm.

Answer 1

∠R= 100°,QR= RP = 5.4cm. 

Step -1: 

Draw a rough sketch of a triangle and label it with the given measurements. 

Step -2: 

Draw a line segment QR of length 5.4 cm. 

Step -3: 

Draw a ray \(\overrightarrow {RX}\) making an angle 100° with QR.

Step -4: 

Draw an arc of radius 5.4 cm from R, which cuts \(\overrightarrow {RX}\) at P. 

Step -5: 

Join P, Q to get the required ΔPQR
