I've looked in a math book that an isosceles triangle has at least two congruent sides. I also know that the words "at least" mean this symbol: $\ge$, which means "is greater than or equal to" or "is no less than." This got me thinking that equilateral triangles can also be isosceles triangles, but is that true?

I noticed that one of the triangles is isosceles, and so I could calculate the other two angles. And so using a result about alternate angles I think, I was able to calculate one of the angles of the triangle of interest.
The solution claims to use the angles corresponding to the same segment are equal, but I'm not su... | 677.169 | 1 |

Barycentric coordinates are a type of homogeneous coordinates that join a point of the plane with respect to the reference triangle of the system. We can define barycentric coordinates using vector calculus or using oriented surfaces and oriented lengths, which can be seen in the first part of this paper. A characteris... | 677.169 | 1 |
A general name for the angular height of a celestial body above the horizon that is determined from a sextant measurement or sight reduction. Angular height is often called "altitude" in other textbooks. When a body is right on the horizon, its height is 0°; when a body is overhead, its height is 90°. The term is used ... | 677.169 | 1 |
