Question

4 select all the digital construction tools that do the same job as a straightedge.
a circle with center through point
b point plotted on an object
c point of intersection
d segment
e line
5 which digital construction tool does the same job as a compass?
a point
b line
c polygon
d circle with center through point
6 this diagram was made using digital construction tools. one of these triangles was made using the polygon tool, and the other was made using the regular polygon tool.
explain what you could do to tell the difference between them.
7 which digital construction tool would help you determine whether point c or point d is the mid - point of segment ab?
a angle bisector
b perpendicular bisector
c perpendicular line
d parallel line

Explanation:

1. A straight - edge is used to draw straight lines and segments. So, segment (D) and line (E) are like a straight - edge.
2. A compass is used to draw circles. The "Circle with center through point" tool (D) does the same job as a compass.
3. Triangles made with the polygon tool and regular polygon tool can be differentiated by checking the side - lengths and angle measures. Triangles made with the regular polygon tool (when set to 3 sides) will be equilateral (all sides and angles equal), while those made with the general polygon tool may not be.
4. The perpendicular bisector tool (B) can be used to determine the mid - point of a segment. If a point lies on the perpendicular bisector of a segment, it is equidistant from the endpoints of the segment. So, using the perpendicular bisector of segment AB, we can check if point C or point D is the mid - point.

Answer:

1. D, E
2. D
3. Check side - lengths and angle measures. Triangles from regular polygon tool are equilateral.
4. B
