# Write a congruence statement for each pair of polygons

In Activity 3, students are invited to reformulate their understanding of triangle congruence by drawing from their experiences with side-angle-side congruence in Activity 2. In side-angle-side congruence, the side opposite the angle between the two given sides will be seen to be congruent to the corresponding side of the second triangle as a consequence of the angle congruence of the two corresponding angles. High School Statutory Authority: Algebra I, Adopted One Credit. Students shall be awarded one credit for successful completion of this course. This course is recommended for students in Grade 8 or 9. Mathematics, Grade 8 or its equivalent. By embedding statistics, probability, and finance, while focusing on fluency and solid understanding, Texas will lead the way in mathematics education and prepare all Texas students for the challenges they will face in the 21st century. The placement of the process standards at the beginning of the knowledge and skills listed for each grade and course is intentional.

The process standards weave the other knowledge and skills together so that students may be successful problem solvers and use mathematics efficiently and effectively in daily life. The process standards are integrated at every grade level and course.

When possible, students will apply mathematics to problems arising in everyday life, society, and the workplace.

Students will use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution.

Students will select appropriate tools such as real objects, manipulatives, paper and pencil, and technology and techniques such as mental math, estimation, and number sense to solve problems. Students will effectively communicate mathematical ideas, reasoning, and their implications using multiple representations such as symbols, diagrams, graphs, and language.

Students will use mathematical relationships to generate solutions and make connections and predictions. Students will analyze mathematical relationships to connect and communicate mathematical ideas.

Students will display, explain, or justify mathematical ideas and arguments using precise mathematical language in written or oral communication. Students will study linear, quadratic, and exponential functions and their related transformations, equations, and associated solutions.

Students will connect functions and their associated solutions in both mathematical and real-world situations. Students will use technology to collect and explore data and analyze statistical relationships. In addition, students will study polynomials of degree one and two, radical expressions, sequences, and laws of exponents.

Then write a congruence statement.

62/87,21 All corresponding parts of the two triangles are congruent. TRIANGLES DAY33 EXTERIOR ANGLE THEOREM: Exterior angle of a triangle equals the Sum of the Determine if each pair of polygons below is congruent. State Yes or No. If No, state (These are trickier) Determine if the two triangles are congruent.

If so, write a congruence statement if not, write NOT Congruent. T a) b). Aug 04,  · In congruent polygons, this means that the corresponding Explain how to write a congruence statement. Provide an example to support your explanation. 4. Write congruence statements for each pair of triangles.

a. D E C K L J b. N R T S O M drAw ConCluSIonS. [] Each pair of polygons is congruent. Find the measures of the numbered angles. [] Name a pair of overlapping congruent triangles. State the postulate which proves the two triangles congruent.

7. Write a Congruence Statement. If there is not enough information, write not enough information. Example) Determine if each pair of polygons are similar.

If so, write the similarity statement and the If so, write the similarity statement and the similarity ratio. Polygons can still be similar even if one of them is rotated, and/or mirror image of the other.

In the figure below, all three polygons are similar. Starting with the polygon on the left, the center polygon is rotated clockwise 90°, the right one is flipped vertically.
