Now, let's set up the proportion to find $z$:ĭivide each side by $2$ to solve for $z$: Now, let's set up the proportion to find $y$:ĭivide each side by $2$ to solve for $y$: Get rid of the fractions by using the cross products property to multiply the numerator of one fraction with the denominator of the other fraction, and vice versa:ĭivide each side by $3$ to solve for $x$: Let's set up the proportion to find $x$ first: Plan Objectives To identify similar polygons To apply similar polygons Examples Understanding Similarity Determining Similarity Using Similar Figures Real-World Connection Real-World Connection 1Similar Polygons Two gures that have the same shape but not necessarily the same size are similar (,). Now we can use this scale factor to set up proportions for the other sides to find the values of $x$, $y$, and $z$. We are given definite values for similar sides in the two quadrilaterals, so let us find the scale factor for the two quadrilaterals:ĭivide both the numerator and denominator by their greatest common factor, $3$, to simplify: If these two quadrilaterals are similar, we would expect the sides to be similar. Geo 7.2 Practice and Homework. Answer Congruent angles: Extended proportions: Work Step by Step First, we identify all the pairs of congruent angles: Now, lets take a look at the corresponding sides in both triangles. ![]() Geo 7.1 Practice and Homework.docx (836k) Peter Wertz, Feb 24, 2016, 4:41 AM. Similar polygons have congruent angles and proportional sides. Practice 7-2 Similar Polygons Are the polygons similar If they are, write a similarity statement, and give the similarity ratio. 7.3: Showing Triangles are Similar: AA-SHORT CHAPTER 7 QUIZ (7.1-7.3) ON FRIDAY, 02/17/17. ![]()
