Right Triangle
The Triangle is a plane closed figure composed by 3 straight lines that do not
intersect, but are joined at their extremities.
A triangle is also a three-sided polygon. A polygon is a closed plane figure composed by a non specified number of straight line segments that join in pairs
at their endpoints. All the right triangle has one of the angles measuring 90 degrees or PI/2 radians. For a triangle, the sum of two sides must be always
greater than the third.
A corner of a triangle is known as a vertex. The opposite side is that side which is opposite to a given vertex. The
adjacent side is that share the same vertex.
The angle is the opening formed by two line segments, connected together at their extremities.
The most common unit of measure is the degree and radian.
The radian is an angular measure of an arc whose value corresponds to the radius of the circle that contains the arc. For the conversion purposes,
1 degree is equals Π/180 radians and 1 radian equals 180/ Π degrees.
the height of the triangle is a straight line segment perpendicular to the baseline that joins in the vertex of the opposite angle. A triangle can have up to three different heights depending on the position of the side taken as the basis.
In a right triangle, taken as base, one of its sides, except for the hypotenuse, the height is equal to another side, perpendicular to the base.
