I assume that we are talking about a "right angled triangle". Guessing the angled bit gets missed in US English.
It means that the Triangle contains a right angle which is to say one of 90 degrees.
A square corner in other words. As to why a right angle is so called wikipedia says:
The term is a calque of Latin angulus rectus; here rectus means "upright", referring to the vertical perpendicular to a horizontal base line.
