Question
(Q1) Consider the two rows of points on the grid below. Count the number of triangles that can be formed using these points as vertices. How many of these triangles are isosceles, or have exactly two congruent sides? Note: Here's an example of an isosceles triangle on the given grid: You don't need to use the tikz code to draw your triangles; you may also use the includegraphics command to insert a picture. (See source in template.)
