Introduction to the Geometry of the Triangle

Subtracting the two equations we obtain the equation of the radical axis of the two circles: L : (a?b)(a?c)x+(b?a)(b?c)y+(c?a)(c?b)z= 0 We rewrite this as x b?c + y c?a + z a?b = 0 There are two points with simple coordinates on this line: P= ((b?c)2: (c?a)2: (a?b)2) and Q= (a(b?c)2: b(c?a)2: c(a?b)2)

What is a platonic triangle?

The Platonic form is the ideal triangle—a figure with perfectly drawn lines whose angles add to 180 degrees. Any form of triangle that we experience will be an imperfect representation of the ideal triangle. Regardless of how precise your measuring and drawing tools you will never be able to recreate this perfect shape.

What are triangles in math?

They are defined as polygons with three edges and three angles. Students as young as preschool can be introduced to triangles, but keeping track of the different types can be difficult. For more definitions and equations before starting on the resources, see the bottom of the page.

What does Plato say about the form of a triangle?

Plato would say that peoples’ attempts to recreate the Form will end up being a pale facsimile of the perfect Idea, just as everything in this world is an imperfect representation of its perfect Form. The Idea or Form of a triangle and the drawing we come up with is a way of comparing the perfect and imperfect.

What is a triangle with one obtuse angle called?

A triangle with one obtuse angle can be classified as obtuse triangle. A right triangle is a triangle with one right angle. Segments PQ and RP are called the legs of the right triangle and segment RQ is called the hypotenuse. The legs form the right angle ? RPQ.
