Triangles and Congruency

A
Triangle
is a closed
figure formed
by three intersecting
lines. Many shapes around
us are triangular signals and
signs. A triangle will need three
to four measurements to be determined,
Try to draw it where just two angles or two
lines are defined. It is the first closed geometry
having an odd number of sides, Equality of the area 

of a circle and a triangle is impossible to decide. The shape
is based on visual and measurement referring to size, Congruent
triangles are identical both in shape and size. Congruency is a
method for the comparison of triangles. Corresponding parts are equal
in congruent triangles, Five congruent rules prove the congruency of the
triangle, and Side-Side-Side correspondence is it is initial. Other congruency rules
are SAS, ASA, AAS, and RHS, It is not sufficient to prove by SSA or ASS. 🔺🔻🔺
