Question 2 - Figure it out (Page 148) Construct the following figure.Okay, here we First create a cross shape (make 90° ) So, that will be points A, C, E, G Then we divide it, making 45° That will be points B, D, F, H And, then we divide it again, making 22.5° Then we alternately join points Let’s do it Steps of Construction 1. Construct 90°: Create perpendicular bisector & extend to both sides. 2. Construct 45°: Bisect the 90° angle & extend to both sides. 3. Construct 22.5°: Bisect the 45° angle & extend to create 8 valley lines. 4. Create a big circle of any radius Mark Tips (S, T...) on the main lines. 5. Create a smaller circle now Mark Corners (A, B...) on the 22.5° valley lines. 6. Connect Tips to Corners. Like connect S to H & A, and so on 7. Shade for 3D effect.
