A triangle has three corners or vertices and three sides or edges which are straight line segments.
Equilateral triangle is a triangle that has equal length on all three sides.
If two sides and the included angles of two triangles are correspondingly equal, the two triangles are congruent. This is called SAS Triangle.
Find the area of a triangle from the given length 3 and breadth 4.
Find the area. Area = l * b/2 = 3 * 4/2 = 12/2 = 6.
Find the perimeter of a triangle from the given side 1, 2, 3.
Find the perimeter. Perimeter = a + b + c = 1 + 2 + 3 = 6.
Find the area of a equilateral triangle from the given length 3.
Find the area. Area = (Sqrt(3) / 4) * l² = (1.73 / 4) * 3² = 0.43 * 9 = 3.87.
Find the area of a SAS triangle from the given length 3 and breadth 4 and angle 28 degree.
Find the area. Area = ½ * l * b * SinC = 0.5 * 3 * 4 * Sin(28) = 6 * 0.27 = 1.62. The above example will clearly illustrates how to calculate the Area, Perimeter of a Triangle, Equilateral Triangle, SAS Triangle manually.
