Question

From a piece of paper cut out an isosceles triangle XYZ with XY=XZ (Fig 6.20).
Fold it such that Z lies on Y. The line XM through X is now the axis of symmetry (which
you will read in Chapter 14). You find that Y and Z fit on each other exactly XY and
XZ are called equal sides: YZ is called the base; Y and Z are called base angles and
these are also equal
Thus, in an isosceles triangle:
(1) two sides have same length.
(ii) base angles opposite to the equal sides are equal.​
