WebThe triangle in which two sides are of equal length are called isosceles triangle. Here length of sides are given as; AB = a cm AC = a cm BC = b cm Note that in Isosceles triangle, the altitude divides the base into two equal parts. So, BM = MC = b/2 Now applying Pythagoras theorem in triangle ABM. WebADD: #^2+#^2= x^2 ( the # represents ANY number, and the x represents the variable) SUBTRACT: ... five and indeed, five squared plus 12 squared, that's 25 plus 144 is 169, 13 squared. So the key of realization here is isosceles triangle, the altitudes splits it into two congruent right triangles and so it also splits this base into two.

The difference between these two definitions is that the modern version makes equilateral triangles (with three equal sides) a special case of isosceles triangles. A triangle that is not isosceles (having three unequal sides…
