SCALENE TRIANGLE #scalene #triangle
Scalene triangle : A triangle where all three sides are in different lengths and all three angles are different measures. Properties of scalene triangl e: 1.All 3 sides are different in length. 2.All 3 angles are different. 3.The sum of all three interior angles is 180 degrees. 4.There are no lines of symmetry. Area of scalene triangle : 1.If height and base are given, then Area A=(1/2)xbxh 2.If the 3 sides are given , then Area A=√(s (s-a)(s-b)(s-c) where s=(a+b+c)/2,where a,b,c are given sides. 3.If two sides and angle is given, then Area A=(1/2)absinθ, where θ is the given angle and a,b are the sides. Construction : 1.Draw a line segment for the longest sides of the triangle. 2.Use a protractor to measure the given angle at one side of the line. 3.Construct a ray that's close to the line. 4.Use a compass and ruler to measure another side of triangle. 5.Put the compass at one end of...
