Review Unit 5- Similar Figures and Angle Relationships

Front

What is a scale on a map?

Back

A scale on a map is a ratio that represents the relationship between a distance on the map and the actual distance it represents in real life.

Front

If the scale on a map is 2 inches = 40 miles, how do you find the actual distance for 4.125 inches?

Back

Multiply the distance on the map (4.125 inches) by the scale factor (40 miles / 2 inches). Actual distance = 4.125 * 20 = 82.5 miles.

Front

What is the actual distance if the distance on the map is 1 3/4 inches and the scale is 1 inch = 100 miles?

Back

Multiply 1.75 inches by 100 miles. Actual distance = 1.75 * 100 = 175 miles.

Front

What is a complementary angle?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is a supplementary angle?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If an angle's complement is 35 degrees, what is the angle?

Back

The angle is 90 - 35 = 55 degrees.

Front

If an angle is 55 degrees, what is its supplement?

Back

The supplement is 180 - 55 = 125 degrees.

Front

What does it mean if two angles are neither complementary nor supplementary?

Back

It means that the sum of their measures is not equal to 90 degrees or 180 degrees.

Front

Find the missing angle if one angle is 43 degrees and they are supplementary.

Back

The missing angle is 180 - 43 = 137 degrees.

Front

Find the missing angle if one angle is 67 degrees and they are complementary.

Back

The missing angle is 90 - 67 = 23 degrees.
