Classify the triangle based on the angle measures:

• Acute

• Obtuse

• Right

Classify the triangle based on both angles and sides:

• Obtuse Isosceles

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 2x + 20 + 9 = x + 21

• 9 + x + 21 = 2x + 20

• 2x + 20 - 9 = x + 21
