Rotations and reflections usually (but not always) change the orientation of a figure. Choosing the right sequence takes practice. Teaching about Classifying Polygons | Houghton Mifflin Harcourt. Create an account to get free access. Prerequisite Skills and Concepts: Students should be able to recognize triangles and quadrilaterals by the number of sides.
We can prove that two figures are congruent by describing a sequence of translations, rotations, and reflections that move one figure onto the other so they match up exactly. Hi Guest, Here are updates for you: LATEST POSTS. If we copy one figure on tracing paper and move the paper so the copy covers the other figure exactly, then that suggests they are congruent. Which polygons are congruent select each correct answer will. To highlight student reasoning and language use, invite groups to respond to the following questions: For more practice articulating why two figures are or are not congruent, select students with different methods to share how they showed congruence (or not). Another special triangle is the isosceles triangle, where only two sides are congruent. Angle B is labeled forty-eight degrees, angle C is labeled forty-nine degrees, angle G is labeled forty-five degrees, and angle H is labeled fifty-two degrees.
Encourage students to explore different ways to classify polygons. You can also ask students to draw different polygons using a straight edge. The square grid can be a helpful structure for describing the different transformations in a precise way. If teaching remotely, use digital images or slides that all students can see and you can freely move around.
For the congruent shapes, ask which motions (translations, rotations, or reflections) students used, and select previously identified students to show different methods. More formally, the figure and its image have the same mirror and rotational orientation. Which polygons are congruent? Select each correct - Gauthmath. ) Within each group, students work in pairs.

Use colorful paper, and write the name of each polygon in the center. Triangle) Can anyone tell me what makes a triangle different from other shapes? Write these properties below the polygon shape. Which polygons are congruent select each correct answer form. For a couple of the triangles that are not translations of the given figure, ask what sequence of transformations would show that they are congruent, and demonstrate any rotations or reflections required. Monitor for different sequences of transformations that show congruence. Identify triangles, quadrilaterals, pentagons, hexagons, and octagons.

Rectangles and squares are similar in many ways: - Both are quadrilaterals (four-sided polygons). D. The corresponding sides and angles are shown equal, therefore, the polygons are congruent. Invite them to share during the discussion. Still have questions? When two shapes are not congruent, there is no rigid transformation that matches one shape up perfectly with the other. Preparation: Prepare an overhead transparency of worksheets 1 and 2. For each question, students exchange roles. For D, students may be correct in saying the shapes are not congruent but for the wrong reason. Unlike in the previous activity, the non-congruent pairs of polygons share the same side lengths. For each of the following pairs of shapes, decide whether or not they are congruent. This activity continues to investigate congruence of polygons on a grid. Does the answer help you?
Download thousands of study notes, question collections. Direct students towards identifying that squares and rectangles both have four right angles, but only squares have four congruent sides. By clicking Sign up you accept Numerade's Terms of Service and Privacy Policy. Divide the class into two groups.

Is not congruent because those are not the same exact size or I'm sorry, the same exact shape and then C. Is not congruent because those are not the same exact size. If Student A claims they are congruent, they should describe a sequence of transformations to show congruence, while Student B checks the claim by performing the transformations. List the properties of a triangle where all students can see: three-sided polygon, contains three angles or corners.
