Introduction: The concepts covered in Triangles Class 9 are important since they are carried on to higher education levels. For this reason, students are advised to learn the concept completely. The purpose of incorporating “Triangles” chapter in the NCERT textbook for Class 9 Maths is to teach students the following concepts: 1. Triangle congruenc...
Learning the congruence of triangles is very important to draw conclusions from the different polygon congruences. It has been used in real life, such as the construction of identical buildings, and so on. The following are the criteria for the congruency of the triangles. 1. 1.1. SAS 1.2. ASA 1.3. AAS 1. SSS 2. RHS
AAS Criteria for Congruency
– Two triangles are said to be congruent to each other if two angles and one side of one triangle are equal to two angles and one side of the other triangle.
Why Are SSA and AAA Congruency rules Not Valid?
1. SSA test is not a valid test for congruency as the angle is not included between the pairs of equal sides. 2. The AAA test also is not a valid test as even though 2 triangles can have all three same angles, the sides can be of differing lengths. This becomes a test for similarity (AA).
RHS Criteria for Congruency
1. If in two right triangles, the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent. 2. RHS stands for Right angle – Hypotenuse – Side.
Isosceles Triangle Property Angles opposite to equal sides of an isosceles triangle are equal. Converse of Isosceles Triangle Property The sides opposite the equal angles of a triangle are equal. To know more about the Properties of Isosceles Triangles, visit here.
Relationship between unequal sides of the triangle and the angles opposite to it. If 2 sides of a triangle are unequal, then the angle opposite to the longer side will be larger than the angle opposite to the shorter side. Triangle Inequality The sum of the lengths of any two sides of a triangle must be greater than the third side.
