Using similar polygons

I remember vividly as an adolescent, I got thrilled and psyched seeing action and sci-fi movies especially those involving large guns and grenades. The first day I ever heard the word 'polygon' in the class, as introduced by my Maths teacher, Mr, using similar polygons.

As you may recall, congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent equal. Whereas, similar polygons have the same shape, but not the same size i. This means that if two polygons are similar, then their corresponding angles are congruent but their their corresponding sides are proportional as displayed in the figure below. Remember, a ratio is a fraction comparing two quantities, and a proportion is when we set two ratios equal to each other. And we can use cross multiplication to solve a proportion. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor.

A circle, cube, or oval is not a polygon. A triangle is a polygon. The capital letter L is not a polygon. Similar polygons involve two mathematical concepts similarity and polygons , and have within them an additional concept, proportion. First look at the angles. Are they the same from one triangle to the other? They are not.

How do you identify similar polygons? Which among the following is a polygon? Taking a short quiz. Are all equilateral triangles similar? If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.

The ratios of the corresponding sides of each polygon can be set equal to each other to form a quadratic equation of this unknown quantity. When making diagrams for similar polygons, careful attention must be given to the labeling of the vertices and the ordering of these labels. Using similar polygons to find missing angles and sides If it is known that two polygons are similar, this can be used to work out the values for unknown sides and angles. As you may recall, congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent equal. Not to worry, nobody is getting shot here, rather you shall go beyond bullet points as the meaning, identification, application, formula as well as examples of similar Polygons would be addressed hereafter.

Everything you need to know on. Two similar quadrilaterals are shown above. For example, using the figure above, the simplified ratio of the lengths of the corresponding sides of the similar trapezoids is the scale factor. The polygons will be named by letters going around the vertices in questions, the first two letters of each will represent the side between these vertices for each polygon and these sides have a proportional relationship.

Apparently, we need just the smallest side; thus, because these polygons are similar, the smallest side of the bigger polygon corresponds with the smallest side of the smaller polygon. Are all congruent polygons similar? In the video below we are going to review how to solve proportions, determine if two polygons are similar by creating scale factors, and learn how to solve for unknown measures. Are all similar polygons congruent?
