Test Geometry Line Segments

Front

What is a ray in geometry?

Back

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

Front

If AB = 2x + 3 and BC = 3x - 5, how do you find the value of x if AC = 38?

Back

Set up the equation: AB + BC = AC. Substitute the expressions for AB and BC, then solve for x.

Front

What is the formula to find the length of a line segment?

Back

The length of a line segment can be found using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

How do you find the length of segment KL if you know the coordinates of points K and L?

Back

Use the distance formula: KL = √((x2 - x1)² + (y2 - y1)²).

Front

What is the relationship between the lengths of line segments AB, BC, and AC in a straight line?

Back

In a straight line, the sum of the lengths of segments AB and BC equals the length of segment AC.

Front

If AB = 11, what does this represent in a geometric context?

Back

AB represents the length of the line segment connecting points A and B.

Front

What is the significance of the variable x in the equations for line segments?

Back

The variable x represents an unknown value that can be solved for to determine the lengths of the line segments.

Front

How can you verify the solution for x in the equation AB + BC = AC?

Back

Substitute the value of x back into the expressions for AB and BC, then check if their sum equals AC.

Front

What does it mean if two line segments are congruent?

Back

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

Front

How do you express the length of a line segment in terms of variables?

Back

The length of a line segment can be expressed as an algebraic expression involving variables that represent its endpoints.
