Question

construct a triangle PQR in which QR = 4.7, angle Q = 45° and PQ plus PR = 8​

Answer 1

Step-by-step explanation:

Steps of Construction:

(i) Draw a line segment which is sufficiently long using ruler.

(ii) Locate points Q and R on it such that QR=4.8cm.

(iii) Construct a line segment QA, sufficiently large, such that ∠Q=45˚ ;Construct a line segment RB, sufficiently large, such that ∠R=55˚, use protractor to measure

(iv) Extend QA and RB to intersect at P.

Then PQR is the required triangle
