Segment Addition Postulate Explained

What does the term 'perpendicular' refer to in geometry?

• A curve that is part of a circle's circumference

• A line that divides another line into two equal parts

• Two lines that intersect at 90 degrees

• Two lines that never meet

Which of the following best describes an 'expression' in mathematics?

• A point that divides a segment into two equal parts

• A combination of variables and numbers with mathematical operations

• A statement that shows two quantities are equal

• A line that intersects another line at 90 degrees

According to the Segment Addition Postulate, if point C lies on segment AB, what is true?

• AC is greater than AB

• AC is equal to CB

• AB is equal to AC + CB

• AB is equal to AC - CB

If segment AB is 9 units long, and segment BC is 5 units long, what is the length of segment AC?

• 5 units

• 4 units

• 14 units

• 9 units

What is a midpoint in geometry?

• A point that lies outside a segment

• A curve that is part of a circle's circumference

• A line that intersects another line at 90 degrees

• A point that divides a segment into two congruent parts

How can you determine if point B is the midpoint of segment AC?

• By checking if B lies outside the segment

• By measuring the lengths of AB and BC and checking if they are equal

• By ensuring B is closer to A than to C

• By drawing a circle with B as the center

If AC is 32 units long and AB is congruent to BC, what is the length of AB?

• 64 units

• 32 units

• 16 units

• 8 units

What does it mean if two segments are congruent?

• They have the same length

• They are part of the same circle

• They intersect at 90 degrees

• They are parallel

If segment NP is represented by the expression 2x + 5, and the total length of segment MP is 32, what is the value of x?

• 5

• 11

• 7

• 9

If PQ is 18 inches long and PM is congruent to MQ, what is the length of PM?

• 18 inches

• 3 inches

• 9 inches

• 6 inches
