A triangle has three sides and three angles ... The three angles always add to 180 ... There are three special names given to triangles that tell how many sides (or angles) are
Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. The types of triangles classified by theirsidesare the followin...

Twotrianglesare said to be congruent if their corresponding sides and angles are also congruent. We need not measure all the sides and angles of two triangles to check if they are congruent or not. There are five conditions for two triangles to be congruent, SSS, SAS, ASA, AAS, and RHS...
As a rule, it is always better to use the sides and angles that are given rather than ones we've just worked out.Example 2 This is also an AAS triangle. First find angle A by using "angles of a triangle add to 180°": A = 180° − 41° − 105° = 34° Now find side ...
In geometry, triangles are shapes with three sides that connect to form three angles. The sum of all angles in a triangle is 180 degrees, meaning that you can always find the value of one angle in a triangle if you know the other two. This task is made e
