Goal: Classify triangles

Activate prior knowledge: we solved for x

Classify triangles by their sides:

• Isosceles triangles: have at least two sides with the same measure.
• Equilateral triangles: all sides have the same measurements.
• Scalene: all sides have different measurements.

Classify triangles by their angles:

• Acute triangle: all angles are acute(less than 90).
• Obtuse triangle: one side is obtuse(more than 90).
• Right triangle: one side is right(exactly 90).

We also identified exterior and interior angles.

Apply: We worked with p.485-486(1-8) as examples on the board.

Homework: p.487(1-10)
