Introduction
In geometry, similar triangles are triangles that have the same shape but not necessarily the same size. This means that corresponding angles are equal and the corresponding sides are in proportion. The SSS similarity theorem states that if three sides of one triangle are proportional to three sides of another triangle, then the two triangles are similar. In this article, we will explore the concept of similar triangles and how the SSS similarity theorem can be used to find the ratio of corresponding sides.
What are Similar Triangles?
Similar triangles are triangles that have the same shape but not necessarily the same size. This means that corresponding angles are equal and the corresponding sides are in proportion. For example, if we have two triangles, â–³ABC and â–³DEF, and the corresponding angles are equal, then the triangles are similar.
The SSS Similarity Theorem
The SSS similarity theorem states that if three sides of one triangle are proportional to three sides of another triangle, then the two triangles are similar. This means that if we have two triangles, â–³RST and â–³RYX, and the ratio of the corresponding sides is equal, then the triangles are similar.
Applying the SSS Similarity Theorem
Let's consider the example given in the problem statement. We have two triangles, â–³RST and â–³RYX, and we are told that they are similar by the SSS similarity theorem. This means that the ratio of the corresponding sides is equal.
Finding the Ratio of Corresponding Sides
We are asked to find the ratio that is also equal to RXRT​ and RYRS​. To do this, we need to find the ratio of the corresponding sides of the two triangles.
Let's start by finding the ratio of the corresponding sides of the two triangles. We can do this by dividing the length of one side by the length of the corresponding side.
Calculating the Ratio
Let's calculate the ratio of the corresponding sides of the two triangles.
