Geometric

Understanding the sum principles of shapes.

Points, Lines and Planes are undefined terms in Geometry whose meaning is accepted without definition. These terms have similar meanings in Geometry as they are used in algebra, like the coordinate plane, ordered pairs and lines .

A perpendicular bisector is a line or a ray which cuts another line segment into two equal parts at 90 degree.

This lesson will look at an example involving an ellipse. The given information will assist in learning how to write the equation of an ellipse in conic sections. This lesson will give a step by step explanation to better understand the concept.

During this lesson we will discussing a triangle and its special segments. A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle has four segments; median, perpendicular bisector, angle bisector, and altitude.

This lesson will explain how to find the ratio of a geometric sequence by looking at an example and going through the steps to solve.

In this video lesson, Mr. Donnelly will be explaining area. This lesson is aligned to the Common Core mathematics for third grade.

Using two terms of a geometric sequence to find u1, r and the general term

In this video lesson, Mr. Donnelly will be modeling problem solving with shape partitions. This lesson is aligned to the Common Core mathematics for the third grade.
