Question 182426
<font face="Times New Roman" size="+2">


You want to draw two similar triangles, meaning their angles are the same measure, but the lengths of their sides are different.


Larger triangle:  1st vertex on one end of a diameter across the sun.  2nd vertex on the other end of the diameter across the sun.  3rd vertex is a point on the surface of the earth representing the location of the observer of the eclipse.


Smaller triangle: 1st vertex on one end of a diameter across the moon.  2nd vertex on the other end of the diameter across the moon.  3rd vertex is a point on the surface of the earth representing the location of the observer of the eclipse (the smaller and larger triangles share this vertex).
