Similar triangles相似三角形similarity ratio相似比 Hypotenuse斜边leg直角边 Judgement theorem判定定理deduction推论 Basic knowledge 1.If the three angles of two triangles are correspondingly equal and three sides are proportional, then these two triangles are similar triangles. 2.The proportion of the corresp...
In similar triangles, corresponding sides are always in the same ratio.For example:Triangles R and S are similar. The equal angles are marked with the same numbers of arcs.What are the corresponding lengths?The lengths 7 and a are corresponding (they face the angle marked with one arc) The...
The two triangles are similar. Find the area of the smaller triangle. Explain how you found your answer.12 in. A = 234 in.226 in. 相关知识点: 试题来源: 解析 Ratio of sides=12:26(6:13) Ratio of area=6^2:13^2 b^2=x 13^2=234 Area=49.85m^2 ...
Similar triangles have corresponding sides that are proportional or related to one another in a constant ratio. What are the corresponding sides and angles? Corresponding means they are in the same position on the shape. Look at the example. Similar trianglesView...
Similar triangles have the exact same shape but not necessarily the same size. The conditions for similarity are 1. Corresponding angles must have the same measure. 2. Corresponding sides must be proportional. (That is the ratios of their corresponding sides must be equal) ...
Two triangles are similar if they have: all their angles equal. corresponding sides are in the same ratio. But we don't need to know all three...
