Question 1 (b) - Figure it out - Page 162 Construct triangles for the following measurements: (b) 25°, 3 cm, 60° First, we draw a rough figure We take the side as base Now, let’s construct it Steps of construction 1. Draw a line segment AB of length 3 cm 2. Since ∠ A = 25° Using protractor, we draw 25° from point A Note: We read the blue mark on protractor 2. Since ∠ B = 60° Using protractor, we draw 60° from point B Note: We read the black mark on protractor 4. The intersection point is Point C. We label the sides Thus, Δ ABC is the required triangle
