• 82*
• 98*
• 75*

What is the measure of angle b?

• 198*
• 56*
• 63*
• 36*

Are the triangles similar? Explain.

• No, because only one angle of the triangles is congruent.
• Yes, because two of the angles are congruent.
• No, because only one triangle has a right angle.
• Not enough information to determine.
