Answer 1

To classify triangles by angles, we use equilateral, isosceles, scalene, acute, obtuse, and right. To classify triangles by sides, we use equilateral, isosceles, scalene.

Step-by-step explanation:

Classifying Triangles

To classify a triangle based on its angles, we can use the following criteria:

• 
  
• An equilateral triangle has three equal angles of 60 degrees each.
• 
  
• An isosceles triangle has two equal angles and two equal sides.
• 
  
• A scalene triangle has all three angles and sides different.
• 
  
• An acute triangle has all three angles less than 90 degrees.
• 
  
• An obtuse triangle has one angle greater than 90 degrees.
• 
  
• A right triangle has one right angle of 90 degrees.

To classify a triangle based on its sides, we can use the following criteria:

• 
  
• An equilateral triangle has three equal sides.
• 
  
• An isosceles triangle has two equal sides and one different side.
• 
  
• A scalene triangle has all three sides different.
