Triangle Similarity and Congruence

Are you comfortable with similarity and congruence?

• Yes

• No

Find the missing angle.

• 30° 
• 31° 
• 32° 
• 33° 

What is the measure of the unlabeled angle of the triangle?

• 90*
• 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.

• Angle 6
• Angle 8
• Angle 1
• Angle 4
