Line AC is 12 inches long. If Point B is located in the center of Line AC, how many inches long is Line BC?
Line AC is 12 inches long. If Point B is located in the center of Line AC, how many inches long is Line BC?
Since Point B is located in the middle of Line AC, it will break Line AC into two equal line segments - Line AB and Line BC. We should divide the original length of Line AC by 2 because we are breaking the original line in half.

Find the length of a line which starts at the point (1,7) and goes till (9,7).
Find the length of a line which starts at the point (1,7) and goes till (9,7).
To solve, simply realize the distance between these points will just be the difference of their x values since their y values stay the same.
These points are on a horizontal line.
Thus,

Find the length of a line connecting the points (1,3) and (7,8).
Find the length of a line connecting the points (1,3) and (7,8).
To solve, simply use the distance formula. Thus,
It is important to remember that with the distance formula, you must keep the order of x2-x1 and y2-y1 consistent. It doesn't matter which point you choose to be 2 and which one you choose to be 1, but once you do, you must keep it in that order for both instances.

How many lines of symmetry does a square have?
How many lines of symmetry does a square have?
A line of symmetry is the imaginary line that you draw through a shape so that you can fold the image over the line and have both halves match exactly. Any regular shape has as many lines of symmetry as it does sides. Since a square has four sides, the correct answer is 4!
