A triangle is one of the basic two-dimensional shapes It is a three-sided figure with three vertices, or points, each of which is connected to the others by a line. Triangles can be classified by their sides, angles, and how they are oriented in relation to one another. The three main categories are right, obtuse, and acute.
The right triangle is a triangle with one right angle. A right triangle has two acute angles and one obtuse angle, and it is the simplest type of triangle because all of the angles are known and can be easily calculated. The Pythagorean Theorem is a formula that is used to determine the lengths of the sides of a right triangle given the lengths of two of the sides.
The obtuse triangle is a triangle with one obtuse angle. An obtuse triangle has one angle greater than 90 degrees and two angles that are both acute angles. The longest side of the triangle is opposite the obtuse angle, and the other two sides have equal length. The obtuse triangle is the most difficult type of triangle to calculate, because the angles and side lengths must be calculated separately.
The acute triangle is a triangle with three angles all less than 90 degrees. An acute triangle has three angles that are all acute angles and three sides that are all of equal length. This type of triangle is the easiest to calculate, because all of the angles and side lengths are known.
Triangles can also be classified by their orientation in relation to one another. A triangle can be either a “scalene” triangle, a “isosceles” triangle, or an “equilateral” triangle. A scalene triangle is one in which no two sides are equal in length. An isosceles triangle is one in which two of its sides are equal in length. And lastly, an equilateral triangle is one in which all three of its sides are equal in length.
