Establishing a purpose of the new lesson The learner demonstrates understanding of key concepts of parallelograms and triangle similarity. The learner is able to investigate, analyse, and solve problems involving parallelograms and triangle similarity through appropriate and accurate representation. The learner describes a proportion. (M9GE-IIIf-1) The learner applies the fundamental theorems of proportionality to solve problems involving proportions. (M9GE-IIIf-2) The learner illustrates similarity of figures. (M9GE-IIIg-1) The learner proves the conditions for similarity of triangles, by AA similarity theorem. (M9GE-IIIg-h-1) The learner proves the conditions for similarity of triangles, by SSS similarity theorem.

The properties that follow show several ways of rewriting proportions that do not alter the meaning of their values. Activity: I CHALLENGE YOU! C. Presenting Examples/ instances of the new lesson 1. Express the following ratios: a. 1 m to 20 cm Solution: 1 m = 100 cm 2. Express the following ratios: d. 1 m to 20 cm Solution: 1 m = 100 cm b. 5 days to 2 weeks Solution: 2 weeks = 14 days e. 5 days to 2 weeks Solution: 2 weeks = 14 days Think-Pair-Share Discussing new concepts and practicing new skills no.1. c. side of an equilateral triangle to its perimeter f. side of an equilateral triangle to its perimeter Solution: Solution: Unlock difficulties: In the proportion a:b = c:d, a and d are called the extremes of the proportion while b and c are the means. In a proportion, the product of the means equals the product of the extremes Unlock difficulties: In the proportion a:b = c:d, a and d are called the extremes of the proportion while b and c are the means. In a proportion, the product of the means equals the product of the extremes Think-Pair-Share Solve for x in the proportionality. 1. = 2. = 3. = 4. 2:3 = 11: (X+3) (2X + 1) : 15 = X : 7 D. Discussing new concepts and practicing new skills no.2 E. Developing Mastery (Leads to Formative Assessment 3.) F. Finding practical application of concepts and skills in daily living Guided Practice (Let’s Do This!) Guided Practice (Let’s Do This!) Are the following ratios proportional? Answer with yes or no If the answer is no, give a ratio, proportional to either of the given ratios. Are the following ratios proportional? Answer with yes or no If the answer is no, give a ratio, proportional to either of the given ratios. Application:Let’s Do More! Application:Let’s Do More! What I ratio? Proportion is the equality of two ratios. Fundamental Rule of Proportion What I ratio? Proportion is the equality of two ratios. Fundamental Rule of Proportion Assessment: Challenge yourself! Assessment: Challenge yourself! H. Evaluating learning Solve for x in the proportionality. 5. = 6. = 7. = 8. Activity Guided Questions 2:3 = 11: (X+3) (2X + 1) : 15 = X : 7 Solve each Proportion. Solve each Proportion. Apply the fundamental law of proportion by finding the missing variable. Write the answer on the blank before the number.

Making Generalization and abstraction about the lesson Illustrative Examples If w:x = y:z, then w y x z provided that x ≠ 0; z ≠ 0. Problem solving Activity If w:x = y:z, then w y x z provided that x ≠ 0; z ≠ 0. Solve each proportion. Solve each proportion. Leave your Leave your answer as a answer as a fraction in simplest fraction in simplest form. form. Analysis Use the SSS Similarity Theorem in writing an ifthen statement to describe an illustration or in completing a figure based on an if-then statement. Write the statements or reasons that are left blank in the proof of SSS Similarity Theorem. SSS Similarity Theorem Two triangles are similar if the corresponding sides of two triangles are proportional If the triangles are similar, write a similarity statement between each pair of triangles.
