3.3 REVIEW: Similar Figures, Scale, Simple Interest, & Net Worth

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is scale in geometry?

Back

Scale is the ratio of the length in a drawing or model to the actual length of the object it represents. It helps in understanding the size relationship between two objects.

Front

How do you calculate simple interest?

Back

Simple interest can be calculated using the formula: Interest = Principal x Rate x Time, where Principal is the initial amount, Rate is the interest rate, and Time is the duration in years.

Front

What is net worth?

Back

Net worth is the total value of an individual's assets minus their liabilities. It represents what a person owns versus what they owe.

Front

If AJ's assets total $150,000 and liabilities are $45,700, what is AJ's net worth?

Back

AJ's net worth is $150,000 - $45,700 = $104,300.

Front

What does it mean for two figures to be proportional?

Back

Two figures are proportional if the ratios of their corresponding sides are equal.

Front

How do you find the scale factor between two similar figures?

Back

The scale factor can be found by dividing the length of a side of one figure by the length of the corresponding side of the other figure.

Front

What is the formula for calculating net worth?

Back

Net Worth = Total Assets - Total Liabilities.

Front

If Brooklyn has assets worth $10,000 and liabilities of $5,377, what is her net worth?

Back

Brooklyn's net worth is $10,000 - $5,377 = $4,623.

Front

What is the relationship between scale and area in similar figures?

Back

The area of similar figures is proportional to the square of the scale factor.
