4. How many triangles are there with vertices from the points shown below? Note, we are not allowing degenerate triangles - ones with all three vertices on the same line, but we do allow non-right triangles. Explain why your answer is correct. Hint 5. How many quadrilaterals can you draw using the dots below as vertices (corners)? Solution 6. How many of the quadrilaterals possible in the previous problem are: a. Squares? b. Rectangles? c. Parallelograms? d. Trapezoids? 2 e. Trapezoids that are not parallelograms?
