	NumberNut.com: Glossary: A
		An acute angle is an angle that has a value greater than 0 degrees but less than 90 degrees (90º).
		An acute triangle is one where all three angles are acute.
		Acute angles have values less than 90 degrees.

	InterMath / Dictionary / Description
		Acute Triangle: A triangle with three acute angles.
		Note: Remember that an acute angle is an angle that is less than 90 degrees but greater than 0 degrees.
		If it were to touch one of these lines, the triangle would then be a right triangle.

	VIAS Encyclopedia: Triangle - General Definitions
		The sides of the triangle are labeled by lowercase letters, corresponding to the particular opposite vertex.
		An equilateral triangle is a triangle with all sides being equal.
		If two sides of a triangle are equal but different to the third side, this triangle is called an isosceles triangle.

	Figures and polygons
		The sum of the angles of a triangle is 180 degrees.
		One of the angles of the triangle measures 90 degrees.
		A right triangle has the special property that the sum of the squares of the lengths of the legs equals the square of the length of the hypotenuse.

	Cool math .com - Types of Triangles
		In the equilateral triangle, all the sides are the same length (congruent) and all the angles are the same size (congruent).
		The isosceles triangle (I can NEVER remember how to spell isosceles) has two sides that are the same length (congruent) and two angles that are the same size (congruent).
		Acute triangles have NO angles greater than or equal to 90 degrees -- all their angles are less than 90 degrees.

		A triangle is a shape with three angles, three sides and three vertices.
		A triangle with angles 20-70-90 is similar to a triangle with angles 10-80-90.
		The longest side of a triangle is smaller than the sum of the two shorter sides.

	Triangle Partition
		If it were true that any triangle could be partitioned into acute triangles then any polygon that could be triangulated with non-obtuse triangles could be further partitioned into acute triangles.
		The remaining triangle, triangle ADC has two angles that are at most 45º and one angle that is at least 90º.
		If the triangle is "flatter" you will need to make CD shorter so that triangles all sort of "bunch together" near C, and so every triangle is acute.

	Lesson Plans
		Triangles can be classified by side (scalene, isosceles, equilateral) or by angle (acute, right, obtuse).
		Elicit from the class the side measurements of one triangle that is obtuse and another that is acute.
		Tell students that in the “Triangles Classification Activity,” they were asked to find the largest side of a right triangle given the two shorter sides.

	The Triangle Figure
		When she placed an acute scalene triangle next to me on her desk, I remembered times as a student that I was asked to sketch an acute scalene triangle to investigate some triangle property.
		To make an acute triangle, we can use the fact that the plane is divided into acute and obtuse regions by the sets of points which yield a right triangle.
		These two reflections may be used to generate a total of four congruent triangles within the same pencil, as long as the third vertex of the initial triangle is not on either of the lines of reflection.

	Altitudes and Orthocenters
		Should this conjecture prove to be true, one could conclude the orthic triangle(formed by connecting the feet of the altitudes) is the triangle of minimal perimeter that can be inscribed in a given acute triangle.
		Thus the orthic triangle is the triangle of minimal perimeter that can be inscribed in a given acute triangle.
		Thus the orthic triangle is the triangle of minimal perimeter that can be inscribed in a given triangle ONLY if that original triangle is acute.
