### UnivHypGeom30: Isosceles triangles in hyperbolic geometry

Isosceles triangles have some special formulas associated to them, which are not obvious.They are also connected directly to the construction of the midpoint(s) of a side.CONTENT SUMMARY: pg 1: @00:11 Definition of isosceles? triangle; theorem (Pons Asinorum); proofpg 2: @03:49 Notation for isosceles triangle; Isosceles triangle theorem @04:59pg 3: @06:17 proof is an application of the Cross lawpg 4: @11:20 connecting isosceles triangle formulas with formulas for equilateral triangles and right triangles; suggested exercise @ 13:26; importance of checking formulas against previous ones @14:04pg 5: @14:34 definition of midpoint; definition of midlinepg 6: @19:47 Midline theorem; proofpg 7: @22:26 Isosceles mid theorem; proof left as an exercise @24:55pg 8: @26:20 Exercise? 30.1pg 9: @29:17 Exercise 30-2; exercise 30-3 @30:27 (THANKS to EmptySpaceEnterprise)
