Can you define an isosceles triangle, cause I'm haivng trouble remembering all the characteristics of one?
Thanks.


Think of base angles being the same measure and 2 sides congruent.

The following are angles in a convex quadrilateral:
Angle A = 78 degrees
Angle B = 121 degrees
Angle C = 99 degrees
What is the measure of the missing angle?
