Indirect Measurement

Front

What are the properties of similar figures?

Back

All angles in similar figures are congruent, and the lengths of corresponding sides are proportional.

Front

How do you find the width of a river using indirect measurement?

Back

Use similar triangles or proportional relationships to calculate the width.

What is the relationship between corresponding angles in similar figures?

Back

Corresponding angles are congruent.

Front

What is the formula for finding the height of an object using shadows?

Back

Height of object / Length of shadow = Height of reference object / Length of reference shadow.

Front

What is the significance of proportionality in indirect measurement?

Back

Proportionality allows us to set up equations to solve for unknown lengths.

Front

What is the definition of indirect measurement?

Back

A method of measuring an object without directly measuring it, often using similar triangles.
