I used a compass to measure and price the line segment. To prove that two lines were congruent I opened the compass and measure one of the line segments and using the amount of opening I compared it to the rest of the lines.

# data[].attributes.body
I marked the end of the line and matched the lengths
Same length

I used a ruler in centimeters to measure each one

# data[].attributes.body
i had used a straight edge to measure the lines to see which ones were congruent

I used a straight edge to measure the line segment.

1. I used a straight edge
2. They have the same measurements

I used a ruler to measure the angle and compare the number I got with another segment

# data[].attributes.body
1. I used a protractor to measure the length of each line segment.
2. They had the same measurement

# data[].attributes.body
I used the index card to mark where each line length was and compare it to the other ones. We agreed as a class that the criteria for proving two line segments to be congruent is to be the same length as each other.

# data[].attributes.body
Two lines are congruent when they are the same length

I used a ruler to measure the length of each line to match each line together.

I used the index card to measure the length of each line segment and compare it the other line segments to see if which were congruent.

i used a ruler to measure

# data[].attributes.body
I used the protractor to measure the lines and proving two line segments are congruent is by finding out their exact measurement and seeing if they're equal

# data[].attributes.body
1. I used a ruler to measure the line segments in millimeters

2. For two lines to be congruent, they must be the same in length.

# data[].attributes.body
I used the index card to check and measure each line segment and found they where congruent by seeing if they had the same measurement

# data[].attributes.body
I used the ruler to see which line measured to the same length.
Two line segments are congruent if they have the same measure.

# data[].attributes.body
I measured each line with a ruler and matched them up by length

# data[].attributes.body
I used a ruler to compare the line segments.
They were both equal in length and that how I knew they were congruent.

# data[].attributes.body
I used an index card and marked the two end points of each segment, and matched it up with the correct line segment.

# data[].attributes.body
I used an index card and would put a dot from one end to the other end of the line segment. That would show me how long it was and then I would like it up against the others and find the matching line.

For a line segment to be congruent they have to be the same measure.

# data[].attributes.body
I user a ruler to measure each line

# data[].attributes.body
I measured one line with a mark on the index card and compared it to the others until I found the match with the same length

# data[].attributes.body
I used the index card to measure each line on the paper and I went around to each line and measured which one matches

Tell me how you used your tool to measure and prove line segment congruence yesterday.

What did we agree on, as a class, the criteria for proving two line segments are congruent?
