Folding Polygons From a Circle

Folding Polygons From a Circle. A circle cut from a regular sheet of typing paper is a marvelous manipulative for the mathematics classroom. Instead of placing an emphasis on manipulating expressions and practicing algorithms, it provides a hands-on approach fro the visual and tactile learner. .

5-3 Concurrent Lines, Medians, Altitudes

5-3 Concurrent Lines, Medians, Altitudes. When two lines intersect at one point, we say that the lines are intersecting . The point at which they intersect is the point of intersection . (nothing new right?). Well, if three or more lines intersect, we say that the lines

GEOMETRY: Chapter 5

GEOMETRY: Chapter 5. 5.3: Medians and Altitudes. A median of a triangle is a segment from a vertex to the midpoint of the opposite side. The three medians of a triangle are concurrent. The point of concurrency, called the centroid , is inside the triangle.

Lesson 1.5

Lesson 1.5. Division of Segments and Angles. Segment Bisector. A point (or a segment ray, or line) that divides a segment into two congruent segments bisects the segment. The bisection point is called the midpoint of the segment. Examples.
