Now i have an equilateral triangle with s is equal to 4 inches.
00:07
That is my side is equal to 4 inches.
00:11
Now, if i just draw this, this is an equilateral triangle with my side equal to 4 inches.
00:20
This is 4 inch.
00:21
Let's say that this is my height, my altitude.
00:25
Okay, this is h.
00:27
Now this is going to divide my base into 2 equal halves.
00:31
So instead of 4, can i write this as 2 and 2? yes, i can.
00:36
This becomes 90.
00:39
Okay.
00:40
Now, since this is an equilateral triangle, this is also going to be 4.
00:43
This is also going to be 4...
