Look at these triangles made with dots. How many dots. How many dots are there in each? Compute the number of dots needed to make the next two triangles.

In the picture below, the lines parallel to each side of the blue triangle through the opposite vertex are drawn to make the big triangle. How many triangles in the picture have the same area as that of the blue triangle.

In the picture below, the lines parallel to each side of the blue triangle through the opposite vertex are drawn to make the big triangle. How many triangles in the picture have the same area as that of the blue triangle? How many of them have the same measures of the blue triangle?

The picture shows a triangle formed by three tangents to a circle. . Calculate the length of each tangent from the corner of the triangle to the point of contact.
