Construct triangle abc such that Ab is 9cm, angle bac is 60 degrees and abc is 45 degrees number 1 .measure length ac
To construct triangle ABC with AB = 9cm, ∠BAC = 60 degrees, and ∠ABC = 45 degrees, follow these steps:
1. Draw a line segment AB with a length of 9 cm.
2. At point A, construct an angle of 60 degrees using a protractor and label the endpoint of the angle as C.
3. At point B, construct an angle of 45 degrees using a protractor and label the endpoint of the angle as C'.
4. Draw a line from C to the midpoint of AB.
5. Draw a line from C' to the midpoint of AB.
6. The intersection point of line segments CC' is the point C.
7. Measure the length of AC using a ruler.
