If it is equilateral, it means it has the same sides. How many sides are there in a triangle?

3 sides in a triangle

  • anonymous
Good! So the whole triangle is 12. Now, divide 12 by 3. What is\[12\div3=?\]
anonymous
  • anonymous
4
anonymous
  • anonymous
Okay so all sides are 4.|dw:1438134827253:dw|

What is the formula for the area of a triangle?
anonymous
  • anonymous
yes. but how do i find the area?
anonymous
  • anonymous
bh/2
anonymous
  • anonymous
It is bh/2.

Notice that we don't know the height. So we will use the Pythagorean Theorem. Are you familiar with that?
anonymous
  • anonymous
okay. so the of the triangle would be \[2\sqrt{3}\]
anonymous
  • anonymous
height
anonymous
  • anonymous
How did you get that?
anonymous
  • anonymous
pythagorean theorem

Can you show me how?

i know its a bit sloppy
anonymous
  • anonymous
So the equation will be.|dw:1438135187194:dw|
anonymous
  • anonymous
so the answer is \[4\sqrt{3}\]
anonymous
  • anonymous
right?
anonymous
  • anonymous
Yes! Good job!
anonymous
  • anonymous
thank you so much
anonymous
  • anonymous
YOU did it yourself. :D
anonymous
  • anonymous
so how would i do it with a 30 60 90 triangle? @mathway

Are you familiar with the 30-60-90 special angle?
anonymous
  • anonymous
yes
anonymous
  • anonymous
Wait are you finding the area for the 30-60-90 triangle?
anonymous
  • anonymous
yes
anonymous
  • anonymous
Use the Pythagorean Theorem.
anonymous
  • anonymous
and the its still bh/2
anonymous
  • anonymous
The area of the triangle we a while ago was a 30-60-90 triangle. :D
anonymous
  • anonymous
okay thanks
anonymous
  • anonymous
Can I see the problem?
