    What is the absolute value of -8 - 2?

    The absolute value of -8 - 2 is | -10 | = 10.

    How do you solve the equation 18 + x = 43?

    To solve for x, subtract 18 from both sides: x = 43 - 18, which gives x = 25.

    What is the significance of undefined terms in geometry?

    Undefined terms, such as point, line, and plane, are foundational concepts in geometry that do not have formal definitions but are universally understood to describe geometric relationships.

    How can you measure a line segment using nonstandard units?

    You can measure a line segment by using a nonstandard unit, such as a paper clip, by placing the paper clips end to end along the segment and counting how many clips fit.

    What is the greatest number of intersection points that can exist with four coplanar lines?

    The greatest number of intersection points with four coplanar lines is 6, which occurs when no two lines are parallel and no three lines are concurrent.

    What is the absolute value of 3 - 9?

    The absolute value of 3 - 9 is | -6 | = 6.

    Why might a four-legged chair rock on a level floor?

    A four-legged chair may rock if the legs are not of equal length or if the floor is uneven at a microscopic level, while a three-legged chair will not rock because three points define a plane.

    How do you classify angles based on their degree measures?

    Angles are classified as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), and straight (exactly 180 degrees).

    What is the absolute value of 7 - 11?

    The absolute value of 7 - 11 is | -4 | = 4.

    How do you construct a copy of a line segment using a compass and straightedge?

    To construct a copy of a line segment, draw a line, set the compass to the length of the original segment, and then use the compass to mark the same length on the new line.

    What is the absolute value of 6 + 2?

    The absolute value of 6 + 2 is | 8 | = 8.

    How do you solve the equation x - 15 = 7?

    To solve for x, add 15 to both sides: x = 7 + 15, which gives x = 22.

    What is the absolute value of 3 - 9?

    The absolute value of 3 - 9 is | -6 | = 6.

    What is the relationship between coplanar points?

    Coplanar points are points that lie on the same plane, while non-coplanar points do not lie on the same plane.

    How do you find the degree measure of an angle?

    To find the degree measure of an angle, you can use a protractor to measure the angle between two rays originating from a common point.

    What is the absolute value of 7 - 11?

    The absolute value of 7 - 11 is | -4 | = 4.

    How do you solve the equation 36 + x = 20?

    To solve for x, subtract 36 from both sides: x = 20 - 36, which gives x = -16.

    What is the definition of a line segment?

    A line segment is a part of a line that is bounded by two distinct endpoints.

    What is the absolute value of -8 - 2?

    The absolute value of -8 - 2 is | -10 | = 10.

    How do you solve the equation x - 23 = 19?

    To solve for x, add 23 to both sides: x = 19 + 23, which gives x = 42.

    What is the absolute value of 3 - 9?

    The absolute value of 3 - 9 is | -6 | = 6.

    What is the definition of a ray in geometry?

    A ray is a part of a line that starts at a point and extends infinitely in one direction.
