ruler
To measure the length of a segment, you would use a straightedge. A straightedge provides a reference line to determine the distance between two points, while a compass is typically used for drawing arcs or circles rather than measuring lengths directly. Although a compass can help in constructing segments of a specific length, it does not measure length itself.
Ruler
It depends. The weight or the length. With the weight you can use a regular scale. With the length you can use a regular ruler.
A meter rule.
A tape measure.
One could use a ruler.
To determine if two segments are congruent, you can measure their lengths using a ruler or a measuring tool. If both segments have the same length, they are congruent. Alternatively, in a geometric context, you can use the properties of shapes or theorems to establish congruence without direct measurement. If the endpoints of the segments are the same or can be shown to coincide through transformations (like translation or rotation), the segments are also congruent.
There are many. Though the ones most commonly used are the ruler and the measuring stick.
A measuring tape should work well in most cases.
To indicate congruent segments in a diagram, you typically use tick marks. Each pair of congruent segments is marked with the same number of tick marks; for example, if two segments are congruent, they might each have one tick mark, while another pair that is also congruent might have two tick marks. This visual representation helps to easily identify which segments are equal in length.
To show that two line segments are congruent on a diagram, use a ruler or a compass to measure their lengths. If the segments are equal in length, you can mark them with the same number of tick marks (e.g., one tick for each segment) to indicate congruence. Additionally, you can label the segments with the same notation (e.g., AB ≅ CD) to emphasize their equality.
To construct segment EF with a length equal to the sum of segments AB (5) and CD (8), first draw segment AB measuring 5 units. Then, from one endpoint of segment AB, use a compass to measure out 8 units to create segment CD. Finally, connect the endpoint of segment CD to the endpoint of segment AB to form segment EF, which will measure 13 units in total.
