What is the distance between two points if it is represented as 11 units on a map where each unit is 10 miles?

Back

The distance is 110 miles.

Front

Define a line in geometry.

Back

A line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

What is a plane in geometry?

Back
