You find the area of a triangle by base times height divided by two.
b * h / 2
The proper way you write it is:
A = b * h
2
A triangle is always 1/2 of a parallelogram. So the triangle's area is the half of a rectangle's area.
Here is a 3 x 3 grid with a triangle.
First, you figure out what the height is. (THE BASE IS NOT ALWAYS THE BOTTOM!)
You have to find out where is it perpendicular. ( REMEMBER, THE HEIGHT IS ALWAYS PERPENDICULAR TO THE BASE.)Then, measure the height which is 3 cm.. Measure the base which is 3 cm.. Multiply the base and the height which is 9 then divide it by 2. You got the area which is 4.5 cm square.A= b *h
2
A= 3 *3 / 2
A= 9 / 2
A= 4.5 cm. square
These are ways to know if the triangle belongs to a square-rectangle, rectangle, and parallelograms.
Square/rectangle - One 90 degree angle.Two 45 degree angles.
Parallelograms- No 90 degree or 45 degree angles
THESE ARE THE TRIANGLES!! NOT THE 4 SIDED FIGURES!!
Do you see this colored word? Press it. I LOVE BASEBALL!! ( THIS IS A LINK!!)
This guy is awesome at explaining the area. I watched it and I hope you will too. :)
If I'm forgetting something please leave a comment. Put an honest comment. OK! I'll appreciate it.

awesome job Kit! but next time try to add color but otherwise good job and the guy is awesome at explaining.
I did have color but it disappeared. -.- Thanks for commenting. :)
Good Job Kit! The scribe can be a helpful tool for studying. The video was helpful too. But one thing is that in the video Jimmy Chang accidentally says that the height(5 ft)is the base.(Second Example: 2:04/2:36) Make sure people doesn't think the height is the base. Plus you should add more color.
Anyways, good job!
Oh, I just noticed that in the video. Thanks Angela and by the way, I did add color then it disappeared.
Gerard this did not help me at all.
