Lesson 9 homework practice similar figures

I am a fan of structured notes that are easy to for students to read, followed by lots of fun activities to keep them engaged and practice their new skills! I believe that the appearance of what we give our students matters greatly. In a day where we are competing with the newest gadgets, we need to grab their attention and interests. Not only is teaching my passion, but also creating materials that students can relate to, find more appealing, and make learning more fun.

Students will practice simplifying expressions using the exponent rules with this coloring activity. There are 20 problems total, separated into two columns. Negative exponents included along with some challenging multi-step problems. Relations, Functions, Domain and Range Task Cards These 20 task cards cover the following objectives: 1 Identify the domain and range of ordered pairs, tables, mappings, graphs, and equations.I quickly survey the class to see if there were any issues with any of these problems and I answer any questions.

Each student will reach into a small paper bag or basket in which I have placed a set of Similar Figures Cards. Teachers with more than 28 students will need to create a few more pairs. The students begin the exercise, each student drawing a card. I think it is also an important aspect of MP6. By picking up the cards while students work, I am ready for the next round as soon as a round is completed. As the rounds progress, the students typically become quicker and more adept at solving the problems, so that the time between rounds decreases.

I recommend completing at least four rounds. With some students, four rounds is typically sufficient. After four turns, I sense that everyone is comfortable with the concepts and ready to move on.

With some students, more than four rounds is beneficial MP8. In the case of an uneven number of students, one student will be without a partner. I give that student the matching card and he or she works alone for that round. I collect the students' Answer Sheets at the end of the activity. During the evening I correct the studemts work, and enter a grade for the activity. This helps to inform my teaching for the next day, cluing me into any problems they might be having as a group or as individuals.

I want my students to gain some practice on skills they will use throughout this unit. The algebraic concepts on which the worksheet focuses include simplifying radicals, multiplying binomials, and factoring. These skills are then applied to solving proportions. Some students have difficulty with these concepts and require considerable help. At the same time, however, I have found that others fly through the work, enjoy working at their own pace, and seem to derive pleasure in their ability to recall and apply these concepts.

Online Scientific Calculator A helpful scientific calculator that runs in your web browser window.Find the measures of the following angles. Explain your reasoning. Measure the longest side of each of the three triangles. What do you notice? Clare says the two triangles are congruent, because their angle measures are the same. Do you agree? Explain how you know. Describe a sequence of translations, rotations, and reflections that takes Polygon P to Polygon Q.

What are the measures of the other two angles? Each diagram has a pair of figures, one larger than the other. For each pair, show that the two figures are similar by identifying a sequence of translations, rotations, reflections, and dilations that takes the smaller figure to the larger one.

For each pair, describe a point and a scale factor to use for a dilation moving the larger triangle to the smaller one. Use a measurement tool to find the scale factor. Explain why they are similar. Draw two polygons that are not similar but could be mistaken for being similar.

Explain why they are not similar. These two triangles are similar. Note: the two figures are not drawn to scale. In each pair, some of the angles of two triangles in degrees are given.

Use the information to decide if the triangles are similar or not. Do you think two equilateral triangles will be similar alwayssometimesor never?

The diagram shows two nested triangles that share a vertex. For each pair of points, find the slope of the line that passes through both points.The lengths of their corresponding sides are proportional. So, the above two rectangles are similar. Perimeter :. Area :. Note :. If the perimeters of two similar figures are in the ratio. If the areas of two similar figures are in the ratio. Example 1 :. The two rectangles given below are similar. Find the perimeter of the rectangle EFGH.

Multiply each side by Perimeter of rectangle EFGH is. Example 2 :. The two parallelograms shown below are similar. Find the perimeter of the parallelogram ABCD. Example 3 :. The perimeters of two similar triangles is in the ratio 3 : 4. The sum of their areas is 75 cm 2. Find the area of each triangle. Solution :. Divide by 25 from each side. Example 4 :. The sum of their perimeters is 35 cm.

Find the perimeter of each triangle. Ratio between the areas of two triangles is.
