Answer:
- ... construction of parallel lines (parallel to AB through C)
- ... width to IJ
Step-by-step explanation:
Construction of parallel lines is accomplished by copying an angle. Here, the steps shown will result in copying the angle IDJ if the distance IJ is marked on the arc through k, then a line drawn through C and the point just marked.
You need tracing paper and pencil
You first trace the triangles you see in the question and follow the rotation instructions.
For example, question 5 says to rotate 90 clockwise
so trace triangle on tracing paper, hold pencil on one point of the corners and rotate the tracing paper clockwise 90.
then you have a new triangle which you can draw out with a ruler.
Hope this somehow made sense, Its hard to give instructions in writing :)
Math uses numbers and equations, and science requires the scientific method and experimentation
