Two Sides and an Angle Not Between Them

Author:John McLain
Are two congruent sides and an angle not between them enough for congruent triangles?

Given the original values, how many triangles are possible?

Check my answer

Keeping the other values the same, make a = 5.5. How many triangles are possible now?

Check my answer

Keeping the other values the same, how big would you need to make "a" so that you can only make one triangle?
