Geometry – Construct a Median of a Triangle

By | November 17, 2016

Construct a Median of a Triangle In this tutorial the students will learn how to use a compass and a straightedge to construct a median of a triangle. A median of a triangle is a line segment that joins the vertex midpoint to the opposite side.  All triangles have 3 medians that intersect at the triangle’s… Read More »

Geometry – Construct an Altitude of a Triangle

By | November 16, 2016

Construct an Altitude of a Triangle In this tutorial students learn how to use a compass and a straightedge to construct an altitude of a triangle. Once the altitude is constructed the students verify that the angle created by the altitude is a right angle using a protractor. A triangle has 3 altitudes. In this video… Read More »
