WebApr 9, 2024 · Let us learn to construct a triangle when the length of two sides and included angle are given through an example. Example: Construct a triangle PQR with PQ = 4 cm, QR = 6.5 cm , and ∠PQR = 60°. The steps of construction are: Step 1: Draw a line QR = 6.5 cm using a ruler. Step 2: Using protractor at Q, draw a line QX making an angle of 60° with QR WebExample 1: Two angles and an included side is∠A = 47º and ∠B = 78º and c = 12.6 units. Find the value of a. Solution: Given: ∠A = 47º and ∠B = 78º ∠A + ∠B + ∠C = 180º ⇒ 47º + 78º + ∠C = 180º ⇒ 125º + ∠C = 180º ⇒ ∠C = 180º - 125º ⇒ ∠C = 55º We shall apply the sine law to find the side of the triangle. a/sin A = c/sin C ⇒ a/sin 47º = 12.6/sin 55º open office download for pc
