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...
The SSS criterion for similarity of triangles states that if all corresponding sides of two triangles are proportional, then the triangles are similar. In other words, if the lengths of the sides of one triangle are in the same ratio as the lengths of the sides of another triangle, then ...
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...
Similarity Ratio is defined as the comparison of two quantities or measurements in terms of their proportional relationship, often used in reasoning about geometric entities and mathematical representations. It involves establishing equal ratios between different lengths or dimensions to draw inferences about...
How can we use the AA (angle-angle) test of similarity to prove that two triangles are similar?a) Which triangles are similar? b) Prove triangle similarity. c) What is the ratio of x to y?Identify the similar triangles....

Example 3: Finding Side Lengths in Right Triangles Find x, y, and z. Find u, v, and w. To estimate the height of a Douglas fir, Jan positions herself so that her lines of sight to the top and bottom of the tree form a 90º angle. Her eyes are about 1.6 m above the ground...
Similar triangles are those triangles which have the same shape, equal pair of corresponding angles and the same ratio of the corresponding sides. Two triangles are said to be similar if two angles in one particular triangle are equal to two angles of another triangle. also two triangles a...
