WebThe SSS similarity criterion states that if the three sides of one triangle are respectively proportional to the three sides of another, then the two triangles are similar. This essentially means that any such pair of triangles will be equiangular (All corresponding angle pairs are equal) also. Consider the following figure, in which the sides ...
WebProof of AA similarity criterion: Consider the equi-angular triangles, ΔABC Δ A B C and ΔDEF Δ D E F Given: ∠A ∠ A = ∠D ∠ D, ∠B ∠ B = ∠E ∠ E and ∠C ∠ C = ∠F ∠ F. To prove: ΔDEF Δ D E F is similar to ΔABC Δ A B C Construction: Assume that AB > DE A B > D E. Take a point X X on AB A B such that AX = DE A X = D E Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures. Consider a hula hoop and wheel of a cycle, the shapes of both these objects are … See more According to the definition, two triangles are similar if their corresponding angles are congruent and corresponding sides are proportional. Hence, we can find the dimensions of one triangle with the help of another triangle. If … See more Let us learn here the theorems used to solve the problems based on similar triangles along with the proofs for each. See more Let us go through an example to understand it better.
