Homothetic centers of three circles and their three
... where three angles of elevation are equal to each other. In section 2, we review an easy construction of homothetic centers of two circles. Using the homothetic centers, we will construct the points from where the angles of elevation are equal to each other for two cones in section 3. A relation bet ...

... Triangles can have special names based on their angles and sides. They can also have more than one name — a triangle can be both acute and isosceles, for example. Here are their descriptions, and check out Figure 1-5 for the pictures: ✓ Acute triangle: A triangle where all three angles are acute. ✓ ...
