Triangle similarity rules
WebIsosceles Triangle. A triangle in which two sides are equal is called an isosceles triangle. For example shown below is an isosceles triangle with AB=AC. • Angle opposite to equal sides of a triangle are equal. • Sides opposite to equal angles of a triangle are equal. • Each angle of an equilateral triangle is 60 o. SSS congruence Rule WebSAS or Side-Angle-Side Similarity. If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar. Thus, if ∠A = ∠X and AB/XY = … Similar figures are two figures having the same shape. The objects which are of … A triangle is the smallest polygon which has three sides and three interior angles.
