Video Transcript

𝐴𝐵𝐶𝐷 is a square where line 𝐴𝐶 and line 𝐵𝐷 are drawn. How many triangles can be found in the square?

There are four triangles. But wait, can you see any more triangles we could draw? We could draw another triangle here. Now, we have five, six, seven, eight. If 𝐴𝐵𝐶𝐷 is a square where lines 𝐴𝐶 and 𝐵𝐷 are drawn, there are eight triangles in the square.
