Learn Class 11 Math - Areas of Parallelograms and Triangles

A triangle is a two-dimensional figure consisting of three lines and corners.

Properties of a Triangle:

• Triangles are polygons with the fewest sides.
• The shape occupies an area bounded by its corners and three line segments in two dimensions.

A closed geometric figure's area on a plane is equal to its coverage.

Considering that a triangle is the simplest polygon, one can calculate the area from the set of triangles that form a finite set. The surface of this hexagon is equal to the sum of its triangular parts since it is a hexagon with two triangular parts.

Area of a Parallelogram

Area of a parallelogram = b×h

Alternatively, the altitude (height) corresponding to 'b' is 'h'.

The height is measured from the base's perpendicular.

A given area can be calculated by multiplying it by the height or base of the missing area.

Area of a Triangle

A triangle's area is (1/2)×b×h

"b" denotes the base, while "h" represents the altitude.

Median of a Triangle

• An edge between a vertice and an opposite vertex is the Median.
• There are three median lines in a triangle, and the point where all three median lines cross is called the centroid.
• Triangles consist of two equal parts divided by the median.
