Lessons
Notes:
In this lesson, we will learn:
- Proof: Area of Triangle =
- Finding the Area of a Triangle Given 2 Sides and the Angle in Between
- Area of Isosceles Triangles
- Area of Equilateral Triangles
- Determining the Areas of Different Triangles
Notes:
- The base and height of a triangle must be perpendicular to each other.
- The traditional formula for the area of a triangle =
- An isosceles triangle has two sides of equal length.
- An equilateral triangle has three sides of equal length and all the inner angles equal to 60°.
- Angles inside a triangle add up to 180°.
- Pythagorean Theorem:
