Hi Emile!
Here is the geometry assignment to do in class on Tue, Sept. 2.
Read paragraphs 32, 33, 34.
Write down the definition of a polygon's diagonal .
Exercises: let us start with 57, 59, 61, 58 (in this order!), and deal with the rest of them later.
Write your solutions in your notepad or as comments to this post.
Good luck!

Here Sasha and Emile study Gelfand-Shen's Algebra and Kiselev's Geometry.

A line is called a diagnol of a polygon if it connects 2 vertices
of the polygon and if vertices are not on the same side
question 1 yes because a equlateral
does have 2 congruent. question 2 no because a isosceles does not have all three diffrent.

If the base is the leg than than the other leg is the altitude that comes straight to the right angle
which is same for the other leg.
If the base is the hypotinuse then the vertex is the right angle.
Good - thanks!
I should correct your wording though: when you say "comes straight to the right angle" or "is the right angle" (in the problem about altitudes of right triangles) you meant "the vertex of the right angle" - remember that an angle is a figure formed by two rays drawn from the same point, but the point you are talking about is the vertex of it.
Hi Emi,
You've answered 57 and 59. Now, could you please describe in words your example to 61 (I know it is easier just to draw a picture, but I want you to try using correct terminology)
and your answer to 58.
