Given ∠P = 70o and ∠Q = 115o. Which of the following part is required to construct triangle PQR?
∠R
QR
PQ
RP
Rajeev followed the following steps to construct a triangle PQR such that PQ=4 cm, QR=5 cm, and RP=7 cm.
Step 1: Draw a line segment of QR of length 5 cm.
Step 2: Draw an arc of 4 cm by taking Q as the centre.
Step 3: Mark the intersecting point as P.
Step 4: Join Q,P, and Q,R to get the required triangle PQR.
Which of the following step is missing for constructing this triangle PQR?
