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...
For instance if the similarity ratio of 2 triangles is3434, then their areas have a ratio of3242=9163242=916 Let's look at the two similar triangles below to see this rule in action. Example 1 It's easiest to see that this is true if you look at some specific examples of real sim...
We are given two triangles. Our objective is to show how the triangles are similar and write a similarity statement. First, to determine if the...
Similar triangles are two triangles with congruent corresponding angles and proportional corresponding sides. To show that shapes are similar, use "~" to write a similarity statement that shows corresponding sides and angles by the order of the vertices. For example, given two triangles, △ABC and...
Before we get into any more detail, we need to cover some basic terminology that will help you understand the unique fractal properties. Self-similar All fractals show a degree of self-similarity. This means that as you look closer and closer into the details of a fractal, you can see a...
How to find Median To find the median, simply line up all your numbers from smallest to biggest, and then pick the one right in the middle. But here comes the tricky part. If you have an odd number set, the median is just the one in the middle. However, if you have an even numb...
Derivatives of tangent and secant Ok, let's draw the mini triangles for tangent and secant: First, we draw the $dx$ mini-triangle on the unit circle (like sin/cos). Next, we slide/scale the mini-triangle to fit on the "secant" radius: $dx$ becomes $\sec(x) dx$ on the secant ...
In propensity score matching, each observation is matched with various other observations that have similar confounding variables (measured by similarity of their propensity scores) but have different exposure values. By comparing the outcome value of an observation to the outcome values of its...
For instance, even if the rule is just “red triangular objects”, none of the bot’s candidate hypotheses are correct, resulting in the bot hindering rather than helping to sort the objects. These examples highlight that it is important to find ways of knowing when one does not know. ...
54 triangles have matching values. This results in a Pearson correlation equal to 0.167. However, because of the strong spatial autocorrelation of each analysis variable, the Lee's L statistic is slightly higher: 0.186. This indicates weak to moderate positive spatial association bet...
