Included angle of sides
WebUsing Two Sides and Included Angle (SAS) Formula. How are the angles of an equilateral triangle related to its area? If two sides and the included angle between two sides is … WebThe three sides of a triangle determine its size and the three angles of a triangle determine its shape. Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal. They are of the same shape and size. There are many conditions of congruence in triangles. Let us discuss them in detail. 1.
