How many triangles are shown, including any overlapping triangles?

To be honest, No idea how this relates to math but i agree the answer is 8, Including overlapping. Real test on the eyes wasn't it?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
