SSS stands for "side, side, side" and means that we have two triangles with all three sides equal.For example:is congruent to: (See Solving SSS Triangles to find out more)If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent....
1.a closed plane figure having three sides and three angles. 2.a flat triangular piece with straight edges, used in connection with a T square for drawing perpendicular lines, geometric figures, etc. 3.any three-cornered or three-sided figure, object, or piece:a triangle of land. ...
The angles that are opposite to the equivalent sides are also equal in measure. Equilateral Triangle A triangle with all 3 sides of an identical length is equilateral. As all three sides are of equal length, therefore, all the three angles will also be identical. Types of Triangles based on...
The first way to classify a triangle is by the length of its sides. A triangle can be classified as scalene, isosceles, or equilateral depending on the length of its sides. A scalene triangle is a triangle with three unequal sides. An isosceles triangle is a triangle with two equal sides...
