11/21/2023 0 Comments Sas congruence theoremtwo triangles are congruent if two angles and an x = QR = TS = 7 y = QO = SO = 9 (Students will raise their hands) Example B: For the triangles in the diagram write the congruence statement, find x. (Electronic pen solution) ΔPQR ΔSTR ∠Q = ∠S ∠R = ∠T ∠ QOR= ∠SOT QR = TS QO = SO RO = TOĢ. ΔDEF, we say that D ∠ is the angle included between ΔABC, we say that A ∠ is the angle included In figures 1 and 2, ΔABC ≅ ΔDEF, because AB,ĪC, and ∠A are equal respectively to DE, DF and Respectively to two sides and the included angle of Two triangles are congruent if two sides and the Who wants to read the Theorem number 1? Theorem 1: (SAS or Side – Angle – Side Theorem) Matching Our behavior and words make us a example and model for the other people. Congruence is important not only in triangles, In mathematics but also in our lives. Nathaniel Branden Sir, I agree, because Integrity is really important, matching our word and actions can bring up good example. (Students will raise their hands) Integrity means congruence. Is the quotation accurate? Do you agree or disagree with this quotation? Kindly explain. Anyone in the class what is the meaning of that quote. What kind of triangle is this? “Yes, sir.” Sir, it is all about Congruent triangles (Students will raise their hands) IdentIdentify the arrow below: (Median, Angel Bisector & Altitude) (Students will raise their hands) Motivation Before we move forward to our new topic. And for our review, I will give you 5 minutes to answer this: Okay, what is it again? Who wants to tell us what our topic was last time? Very good. Class Secretary, if you may.” (The class secretary announces the absentees) Review Class, do you still remember the topic of our last class discussion. Balingit will lead the prayer.) Checking of Attendance “Before we begin, let us first identify the absentees. Balingit, kindly lead the prayer for today’s online class. LEARNING PROCEDURE Teacher’s Activity Student’s Activity Greetings “Good Morning, Grade 12 Magiting students.” “Good morning, sir.” Prayer “Ms. SUBJECT MATTER Topic: Congruent Triangle Learning Resources: Google Meet – meet.google/wqg-zxmx-qha Learning Materials: PowerPoint Presentation III. OBJECTIVES At the end of the lesson, the students will be able to: Derive and state the different triangle congruence postulates and Apply the definition and the congruence postulates to show congruence between triangles II.
