4. What are the different criteria for the congruence of triangles?
The following are the Criteria for the coherence of the triangle.
SSS Congruence Criteria - If the three sides of one triangle are equal to the three sides of another triangle, then these two triangles are parallel. If all the sides are the same, then the corresponding angles should also be the same.
SAS Congruence Criteria - Axiom: Two triangles are aligned when two sides and the inserted angle of the one triangle is equal to the corresponding sides and the inserted angle of the other triangle.
ASA Congruence Criteria - Two triangles are aligned when two angles and the inserted side of one triangle is equal to two parallel angles and the combined side of the other triangle.
AAS Criteria of Congruence - Two triangles are said to be compatible when the two angles and one side of one triangle are equal to two angles and one side of the other triangle.
RHS Congruence Criteria - If the two right triangles of the hypotenuse and one side of one triangle are always equal to the hypotenuse and one side of the other triangle, it means that the two triangles are parallel. RHS stands for right angle - Hypotenuse - Side.
5. On what basis and how can triangles be classified?
Based on the angle, the triangles can be divided into 3 types in the chapter Triangles:
Right, Angle Triangle 90 ° Angle Triangle. For example, if a right-angled triangle has 2 equal sides, then it is called the Isosceles Right Triangle, and the two basic angles measure 45 ° each.
The Obtuse Triangle is a triangle with one of the inner angles measuring over 90 °.
A triangle with all angles less than 90 ° is called the Acute-Angled Triangle.
