Answer 1

if 2 sides of triangle are congruent, then the angles opposite those sides are congruent

Question 2

39 converse of the isosceles triangle theorem

Answer 2

if 2 angles of triangle are congruent, then the sides opposite to those angles are congruent

Question 3

40 coincidence theorem

Answer 3

altitude, median, angle bisector, perpendicular bisectors are all the same in isoscles triangles

Question 4

40 theorem 4-2 if a line or a line segment bisects the vertex

Answer 4

if a line or a line segment bisects the vertex of an isosceles triangle, then it is also a perpendicular bisector of the opposite side

Question 5
