How many triangles are there in the following figure PQRS? A rectangle PQRS with diagonals PR and QS intersecting, and a horizontal line segment connecting the midpoints of sides PS and QR

Explanation

Triangle made of one figures = 6 Triangle made of two figures = 3 Triangle made of three figures = 2 Triangle made of four figures = 1 So, total number of triangles = (6 + 3 + 2 + 1) = 12
