Module 1 Lesson 3 - Line Segments

Front

What is a line segment?

Back

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

Front

How do you find the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

Front

What is the midpoint of a line segment?

Back

Front

If XY = 8.75 ft, what is the length of XY in mixed number form?

Back

Front

What is the formula to calculate the length of a line segment on a number line?

Back

Length = |x2 - x1|, where x1 and x2 are the coordinates of the endpoints.

Front

What does it mean for two line segments to be congruent?

Back

Two line segments are congruent if they have the same length.

Front

If the length of a line segment is 13.2, how would you express this in decimal form?

Back

13.2 is already in decimal form.

Front

What is the significance of rounding in measurements?

Back

Rounding is used to simplify numbers to make them easier to work with, especially in measurements.

Front

How do you solve for an unknown length in a line segment equation?

Back

Isolate the variable using algebraic operations to find its value.

Front

What is the relationship between the lengths of line segments in a triangle?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side (Triangle Inequality Theorem).
