ACT Prep: Estimating Line Segment Lengths

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that in any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

If line segments are collinear, how do you find the total length?

Back

To find the total length of collinear line segments, simply add the lengths of the segments together.

What is the relationship between parallel line segments and their lengths?

Back

If two line segments are parallel, their lengths can be compared, but they do not affect each other's lengths directly.

Front

How do you determine the length of a line segment when given two segments that are collinear?

Back

Add the lengths of the two segments together to find the total length of the line segment.

What is the significance of the collinearity of points in geometry?

Back

Collinearity of points means that the points lie on the same straight line, which affects how we calculate distances between them.

Front

What is the formula for finding the length of a line segment in a triangle?

Back

In a triangle, the length of a line segment can be found using the Triangle Inequality Theorem, ensuring that the sum of the lengths of any two sides is greater than the third.
