the midpoints of the sides of a triangle are (1,1),(4,3),and (3,5). find the area of the triangle. what is the answer and can u explain how u got it step by step? please...
The triangle formed by connecting the midpoints is similar to the original triangle but with all lengths half the original. Therefore the area of the triangle is four times the area of the little one inside (1/2) b h = 4 (1/2)(b/2)(h/2)
check for typos. I bet the original was supposed to be a right triangle.
