Congruent Triangles Definition Geometry. Under this criterion if the two sides and the angle between the sides of one triangle are equal to the two corresponding sides and the angle between the sides of another triangle the two triangles are congruent. Congruent triangles two sides and included angle sas definition.
Under this criterion if the two sides and the angle between the sides of one triangle are equal to the two corresponding sides and the angle between the sides of another triangle the two triangles are congruent. The equal sides and angles may not be in the same position if there is a turn or a flip but they are there. See congruent for more info congruent triangles.
Two triangles are said to be congruent if all 3 of their angles and all 3 of their sides are equal.
This is one of them hl. If two sides of a triangle are congruent then they have the same measure. When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. In the triangle shown in figure 1 segments ab and ac are congruent.
