Constructing angles and bisectors
Steps for congruent angles
1. Use ray tool and construct ray AB and ray AC to form angle BAC.
2. Use ray tool and create a ray under angle ABC this ray should be DE.
3. Use compass tool and create a circle that is centered at A and passes through C.
4. Use the compass tool and copy this circle and move center to point D.
5. Use the intersect tool to create the point F the intersection of the circle and ray DE.
6. Use the intersect tool and create the intersection of ray AB and the circle centered at A this will be point G.
7. Use the compass tool and set radius from point C to point G, then center that circle at point F.
8. Create the intersection of circles centered at D and F to form point H.
9. Use ray tool and create ray DH, to form angle HDE.
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.
11. Use select tool and drag around points in both angles what do you notice?
