Find the third side of an isosceles triangle if the lengths of the other two sides are 5 cm and 2 cm.
In an isosceles triangle, the sides are equal in length. The problem is given two sides, one of which is lateral, the other is the base.
To determine which side of the triangle is lateral, we use the rule:

Geometry
Geometry, in a modern sense, is the art of proving that any two triangles are congruent; and therefore, by extension, all triangles are congruent. However, there are many different branches of geometry involving the study of objects that failed to be triangles, objects that wanted to be triangles but couldn't... | 677.169 | 1 |
