π΄π΅πΆπ· is a rectangle where line π΄πΆ and π΅π· are drawn. How many triangles can be found in the rectangle?

We know that π΄π΅Cπ· is a rectangle. π΄, π΅, πΆ, π·, letβs connect those points: line π΄π΅, line π΅πΆ, πΆπ·, and π΄π· or π·π΄. And two diagonal lines are drawn, lines π΄πΆ and π΅π·. We have to count the number of triangles that have been made. There we have one triangle, two, three triangles, four. If lines π΄πΆ and π΅π· are drawn in rectangle π΄π΅πΆπ·, you can find four triangles inside the rectangle.
