这种比例 k>0 称为这两个三角形之间的相似比(相似比率ratio of similitude)。注意比例的分子和分母,对换位置则变为倒数。 三角形相似,记作 \Delta ABC \sim \Delta A^\prime B^\prime C^\prime ,隐含的顶点对应关系 A\leftrightarrow A^\prime, B\leftrightarrow B^\prime, C\leftrightarrow C^\prime...
What is Similarity of triangles? The similarity of triangles can be defined based on their properties. Two triangles are similar, if (i) their corresponding angles are equal and (ii) their corresponding sides are in the same ratio (or proportion). These two are the main conditions for the s...
3. Corresponding Sides of Two Similar Triangles are in the Ratio of 1:2. If the Area of the Small Triangle is 16 sq. cm, then the Area of the Large Triangle is: (a) 30 sq.cm. (b) 6 sq.cm (c) 7 sq.cm. (d) 4 sq.cm Answer: d Solution:Let A1 and A2 are areas of the...
THEOREM 6:The ratio of areas of two similar triangles is equal to the square of the ratio of their corresponding sides.Construction: Two triangles ABC and PQR are drawn so that, ΔABC ∼ Δ PQR.To Prove:ar ABCar PQR=AB2PQ2=AC2PR2=BC2QR2ar ABCar PQR=AB2PQ2=AC2PR2=BC2QR2...
the necessary conditions for physical similarity of two phenomena—for example, phenomena experienced by an actual object and by a model of it. Similarity criteria consist in the equality of certain dimensionless quantities, called the characteristic numbers, for the phenomena in question. The numbers...
