Question 109308

The word isosceles is pronounced "{{{eye-sos-ell-ease}}}" with the emphasis on the 'sos'. It is {{{any }}}{{{triangle}}} that {{{has –two- sides- the –same- length}}}. 

If {{{all }}}{{{three}}}{{{ sides}}} are the {{{same}}}{{{ length}}} it is called an {{{equilateral }}}{{{triangle}}}. Obviously all equilateral triangles also have all the properties of an isosceles triangle.

{{{Properties}}}

1. The {{{unequal}}}{{{ side}}} of an isosceles triangle is usually referred to as the '{{{base}}}' of the triangle. 

2. The {{{base}}}{{{ angles}}} of an isosceles triangle {{{are}}}{{{ always}}}{{{ equal}}}. 

3. When the {{{3rd}}} angle is a {{{right}}}{{{ angle}}}, it is called a "{{{right- isosceles- triangle}}}". 


So, the answer to your question will be:

An isosceles triangle will {{{sometimes}}} have a right angle.
