Rules of congruence for triangles Class 7 Maths Five main rules of congruency for triangles are as follows: Side-Side-Side (or SSS): SSS rule states that two triangles are congruent if all three sides of one triangle are comparable to the corresponding three sides of the second triangle. Side-Angle-Side (or SAS) - rule states that two triangles are congruent if any two sides and angles included between the sides of one triangle are equivalent to the corresponding two sides and angles contained between the sides of the second triangle. Angle-Side-Angle (or ASA) - rule states that two triangles are congruent if any two angles and sides included between the angles of one triangle are comparable to the corresponding two angles and sides included between the angles of the second triangle.

AAS is analogous to ASA in that two angles and one side from two separate triangles

What is Autotrophic Nutrition?   The word “Autotrophic” is the combination of two terms – Auto (self) and Tropic (nutrition), and the exact definition is self-nutrition. In the presence of sunlight, an organism creates its own food from basic inorganic materials such as water, carbon dioxide, and mineral salts. The nutritional pattern of all green plants is autotrophic. Autotrophic species have a green pigment called "chlorophyll" that aids in the absorption of solar energy. With the aid of carbon dioxide, water, and solar energy, they produce their own food through photosynthesis.
