Repeat?!

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]

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

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.

no..they are slightly different..observe carefully..

Hmm well I used exactly the same methods to solve them

Alan Liang - 8 years, 4 months ago

how are they same?

Saurabh Dubey - 8 years, 4 months ago

Strange....................... :)

This is also the same as this question: https://brilliant.org/i/IRMRjd/

I got chord in a semicircle in level 2 geometry,and it was a 40-pt question.Why?
