LEARNING OUTCOMES 

1.  Students will be able to identify different types of triangles
2. Students will be able to classify triangles based on side length 
3. Students will be able to understand the properties of triangles

NOTE 

A triangle is a polygon with three sides and three angles. Here are some key points:

Properties:

1. Three sides: A triangle has three sides of varying lengths.

2. Three angles: A triangle has three angles that add up to 180 degrees.

3. Sum of angles: The sum of the interior angles of a triangle is always 180 degrees.

Types:

1. Equilateral: All sides are equal.

2. Isosceles: Two sides are equal.

3. Scalene: All sides are unequal.

4. Right: One angle is 90 degrees.

5. Obtuse: One angle is greater than 90 degrees.

6. Acura: All angles are less than 90 degrees.
