This section outlines and explains the criteria for the similarity of triangles. These help us recognize the angle-side relationships in triangles. 15. Ans: When two angles from one triangle are equivalent to two angles from another triangle, the two triangles are said to be comparable. Two similar triangles are related to each other by a similarity factor, s. This means that if a triangle PQR has sides of length p, q, and r, then the triangle similar to PQR would have dimensions of their sides as sp, sq, and sr. Two triangles are said to be congruent if their corresponding sides and angles are equal in lengths and measures, respectively. State whether \[\text{EF }\!\!|\!\!\text{ }\!\!|\!\!\text{ QR}\] for \[\text{PE = 3}\text{.9 cm, EQ = 3 cm, PF = 3}\text{.6 cm}\] and \[\text{FR = 2}\text{.4 cm}\], Given, \[\text{PE = 3}\text{.9 cm, EQ = 3 cm, PF = 3}\text{.6 cm}\],\[\text{FR = 2}\text{.4 cm}\], $\dfrac{\text{PF}}{\text{EQ}}$ $\text{=}$$\dfrac{\text{3}\text{.9}}{\text{3}}$\[\text{ }\!\!~\!\!\text{ = 1}\text{.3}\], $\dfrac{\text{PF}}{\text{FR}}$ \[\text{=}\] $\dfrac{\text{3}\text{.6}}{\text{2}\text{.4}}$ \[\text{= 1}\text{.5}\], Hence, $\dfrac{\text{PE}}{\text{EQ}}$ \[\ne \] $\dfrac{\text{PF}}{\text{FR}}$.
