Select your language EnglishSpanish The perimeter of an isosceles triangle is obtained as the addition of the three sides of the triangle. Having two equal sides, the perimeter is twice the repeated side (a)...

Select your language EnglishSpanish Some classical triangle centers are: Centroid (G) Orthocenter (H) Circumcenter (O) Incenter (I) Centroid of a Triangle The centroid of a triangle (or barycenter of a triangle) G is the...

Select your language EnglishSpanish The isosceles triangle is a polygon of three sides with two equal sides. The other side unequal is called the base of the triangle. Therefore, the angles will also be...

Select your language EnglishSpanish The median of a triangle is a line segment that joins one of its vertices with the center of the opposite side. Every triangle has three medians (ma, mb and...

Select your language EnglishSpanish The altitude of a triangle, or height, is a line from a vertex to the opposite side, that is perpendicular to that side. It can also be understood as the...

Select your language EnglishSpanish The basic elements of a triangle are: Vertices: points where two sides meet. It has 3 vertices (A, B, and C). Sides: line segments that join two consecutive vertices of...

Select your language EnglishSpanish Heron’s Formula gives the area of a triangle when we know all three sides. The area is calculated from the semiperimeter of the triangle, s and the length of the...
