The first way to classify a triangle is by the length of its sides. A triangle can be classified as scalene, isosceles, or equilateral depending on the length of its sides. A scalene triangle is a triangle with three unequal sides. An isosceles triangle is a triangle with two equal sides...

Two triangles are said to be congruent if three sides and three angles of one triangle are congruent with the corresponding sides and angles of the other triangle. Symbol of Congruence Congruence is represented by the symbol “≅.” Since congruence in objects implies equal shape and size; the...
In geometry, triangles are shapes with three sides that connect to form three angles. The sum of all angles in a triangle is 180 degrees, meaning that you can always find the value of one angle in a triangle if you know the other two. This task is made e
