1. Use ray tool and construct ray AB and ray AC to form angle BAC.[br]2. Use ray tool and create a ray under angle ABC this ray should be DE.[br]3. Use compass tool and create a circle that is centered at A and passes through C.[br]4. Use the compass tool and copy this circle and move center to point D.[br]5. Use the intersect tool to create the point F the intersection of the circle and ray DE.[br]6. Use the intersect tool and create the intersection of ray AB and the circle centered at A this will be point G.[br]7. Use the compass tool and set radius from point C to point G, then center that circle at point F.[br]8. Create the intersection of circles centered at D and F to form point H.[br]9. Use ray tool and create ray DH, to form angle HDE.[br]10. Use angle measure tool and measure angle CAG(make sure you go in that order) and then measure angle FDH also in that order.[br]11. Use select tool and drag around points in both angles what do you notice?[br]
