6.7: Areas of Triangles and Quadrilaterals

These are problems that you should do to test how much you understand ( just do these problems when you finish reading the tips for remembering the martirals )

Practice Problems






















In this section 6.7, you will learn how to find the areas of Triangles and Quadrilaterals.
This section contains 3 parts: examples, tips and problems. All these are instructed in the simplest way so that you can understand the lesson easily. And you'll be suprised that it's easier than what you thought!

First, follow these examples.

Examples


1) Area of a Parallelogram


























2) Area of a Triangle

3) Area of a Trapezoid

4) Area of a Kite ( the same as area of a Rhombus )

5) Area of a Rectangle

Ok, I'm sure that now you absolutely understand how to use the formulas. Besides, remembering these formulas is also very important. But for somebody, it'll be very hard and spend a lot of time remembering them so these are the useful tips that can make you be a super memorized-Maths student.

How to better understand the materials?

Do homework ( if you have more times, do more extra problems) for each lesson you have learnt.

If you have troubles with problems, think ..think before asking for help. This way will make you a better thinker in the long run.

Review the mistakes in our quizzes, tests, homework or any problems in our class so that we won’t make any same mistakes.


How to remember the formulas?

The best way to remember is to keep on saying the formulas while you are writing down the formulas.

You can remember them by writing down the formulas as much as you can without looking at.

You can write the formulas on notes with bright color and paste it on everywhere that you often see them.

Practice problems ( they're on the top, there're some problems so we have to move the "Practice Problems" to the top of the section.Sorry)
