Isosceles

A triangle in which two sides have the same length.

Remember to spell isosceles with an SOS in the word.

An isosceles triangle has 2 sides and internal angles which will be the same

I sock em in these (isosceles) (in of a pair of socks the same length) but I need to send out an SOS for another pair of socks (spelt with an SOS).

 

Examples
