Class 7 Maths Chapter 6 Triangles & its Properties – Important Topics

Triangle: A three-sided polygon is called a triangle. The sum of all the internal angles of a triangle is 180 degrees. The different types of triangles are:

Equilateral Triangle – It has all of its sides and angles equal.
Isosceles Triangle – Any two angles and two sides are equal.
Scalene Triangle – All the three sides and angles are different.
Right triangle – Any one of the angles is a right angle.

Congruence of Triangles: If two triangles are similar in certain aspects, they are said to be congruent. Some of the conditions of congruency is given below.

SSS (Side-Side-Side) – Two triangles are said to be congruent by SSS condition if all three sides are equal.
SAS(Side-Angle-Side)- Two triangles are said to be congruent by SAS condition if their two sides and 1 angle are equal.
ASA(Angle-Side-Angle)- Two triangles are said to be congruent by ASA condition if their two angles and 1 side are equal.
AAS(Angle-Angle-Side)- Two triangles are said to be congruent by AAS condition if their two angles and 1 side are equal.
RHS (Right angle- Hypotenuse-Side)- If the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.
