  • AIM: Classify Triangles Do Now Weekly Quiz #12 1
  • Polygon 2
  • Anticipatory Set: Write the definition of each type of angle and then draw each type of angle. Acute Angle Right Angle Obtuse Angle Straight AngleDefinitionDrawing 1.) Draw an additional line segment that will change the acute, obtuse, and right angles into triangles. 2.) Why can the straight angle not be changed into a triangle if you drew only one additional line segment? 3
  • Classifying Triangles by Angle Measures1.) Acute Triangle: A triangle where all angles are acute.2.) Obtuse Triangle: A triangle that has one obtuse angle.3.) Right Triangle: A triangle that has one right angle.Classifying Triangles by Side Lengths4.) Scalene Triangle: A triangle that has no congruent sides.5.) Isosceles Triangle: A triangle that has at least twocongruent sides.6.) Equilateral Triangle: A triangle that where all of the sidesare congruent. 4
  • THINK-PAIR-SHAREClassify each triangle according to its sides and angles. a.) b.) 5
