2nd ESO ART. UNIT 7.3 Geometric Construction of Triangles

A triangle is a plane figure limited by three straight lines that intersect in pairs. It has three sides and three angles. The sum of the angles is 180 degrees. Each side of the triangle is shorter tan the sum of the other two and longer tan their difference.

Although we do not have the videos in English version, we can have a help with the Spanish version ones.

Constructing a triangle when we know two sides and the angle they form



Constructing a triangle when we know one side and the adjacent angles



Constructing a rectangle triangle when we know one leg and the adjacent acute angle
