Discusses the properties and types of triangles, explaining that a triangle is a closed figure with three sides and angles. It categorizes triangles into equilateral, isosceles, scalene ...

The techniques used are useful for solving all kinds of other geometry problems ... These are the base angles. The base angles are opposite the equal sides. An equilateral triangle has three ...

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles. Trigonometry is found all throughout geometry, as every straight-sided shape may be ...

In some real-world settings, taxicab geometry is more convenient, and more relevant, than Euclidean geometry. Engineers use it when planning the most efficient paths for robots to take when navigating ...

So that can't be a triangle because a triangle has to have three straight sides. Great work, Math Mights, on being triangle detectives. I liked the way that you were able to determine triangles ...

You might have already passed that silly course with a title something like "Introductory Algebra and Trigonometry." It covered a bunch of stuff, but the important part was that the class was a ...

And two triangles with equal sides always have equal angles. Geometry problems from the IMO are much more complex than this toy problem, but fundamentally, they have the same structure.

By Kenneth Chang A couple of weeks ago, I wrote about a viral math problem — 8÷2(2+2 ... Next, choose a line to be the second side of the triangle. At first, you might think there ...
