Repeat?!

Alan Liang Shared by Alan Liang 17, USA · 2 years ago

Why is it that for problem 1 and 4 in level 3 Geometry that they are essentially the same problem?

[Clarification: Note that not everyone receives the problems in the same order, or must have received these problems. We are referring to [chord in a semicircle](https://brilliant.org/i/3Knb5M/) and [four points on a semicircle](https://brilliant.org/i/lhsb38/). - Calvin]

The ratios are different. In the 1st problem, the ratio is \( 1: 2\), which allows for a 1 line solution.

In the 4th problem, you're asked to consider the more general case, where I used a ratio of \( 1: 4\). Of course, you can use the same generalized approach to solve the first problem.
