Hello again, dgen,

I've given this to you in other posts. Remember this rule: The largest angle is opposite the longest side. Using this rule, you can easily tell

Same as #1

You have an isosceles triangle here. The base angles are congruent. Looks like the base angles are 60 degrees each.
What is the sum of the measures of the angles of a triangle? Subtract the two base angles and you have the vertex angle.
