Our Geometry department is customized to narrow the scope to the most detailed topics like Circles, then expand to include multiple areas of specialization to achieve comprehension of context within the Mathematics department. Coverage in this topic includes examination of Constant Pi and Lines Tangent to provide proficiency from basic understanding to advanced concepts. In our lessons Radius of a Circle and Area of Circles, you will attain strong foundational skills on which to enhance and perfect. Parts of a Circle is a lesson planned to explore applications and properties of a circle. For example, there is a special Relationship Between a Chords, Diameters, and Minor Arcs of a Circle, which might be useful when making proofs about Inscribed Quadrilaterals. Enrich your mathematical skills with Circles and elevate your comprehension of concepts, theories and application.​
