Transformations smpk gs
This document discusses different types of transformations in mathematics. It defines a transformation as a change in position or orientation of a figure that results in an image of the original. Translations move a figure along a straight line without turning. Reflections flip a figure across a line. Rotations turn a figure around a point. Dilations change the size of a figure. The document provides examples of identifying transformations and graphing translations and reflections on a coordinate plane.
Chapter 9 PARALLEL LINES SMPK PENABUR GADING SERPONG
This document discusses parallel lines and their properties. It defines parallel lines as lines that do not intersect and always have the same distance between them. It then covers different types of angles formed when parallel lines are intersected by a transversal line, including corresponding angles, alternate interior angles, alternate exterior angles, consecutive interior angles, and consecutive exterior angles. It states properties of these angles, such as corresponding angles being congruent and alternate interior angles and exterior angles being congruent. Examples are given of finding missing angle measures using these properties.
Social arithmetic
The document provides definitions and examples for key mathematical terms related to profit/loss, discounts, interest, and weight measurements. It defines terms like cost, selling price, profit, loss, marked price, discount, interest, interest rate, simple interest, compound interest, bruto, netto, and tarra.

EXERCISE Chapter 9 parallel lines
The document contains a series of math word problems and geometry exercises involving angles, triangles, trapezoids, and algebraic expressions. Students are asked to identify geometric features of shapes, calculate unknown angle measures, and solve for unknown variables in expressions. They must apply properties of angles, triangles, parallel lines, and algebraic operations to determine the requested values.
Relationship of angles
This document contains 10 problems about relationships between angles including complementary, supplementary, and ratio relationships. It asks the reader to find missing angle measures based on information provided about other angles. For each problem it provides space for the answer but no worked solutions are shown. Overall it focuses on developing understanding of complementary, supplementary, and ratio relationships between angles.

It provides equations relating angles to their complements and supplements to be solved for the unknown value or measure of an angle.
Problem solving sets
There are several word problems presented involving sets and counting principles. They can be summarized as follows:
1) The problems involve counting elements in sets based on given information such as the number of elements in overlapping and separate sets.
2) Questions ask how many elements are in the intersection or union of sets, or how many elements satisfy single or multiple criteria.
3) The context of the problems involves surveys, students, products, newspapers, and other everyday scenarios to count people or items in categories.
Linear Equation with One Variable (LEOV)

Preparation mid
Michael went to the library for the first time on September 3rd. Andi went every 2 days, Nathan every 3 days, and Michael every 4 days. They ask how many times each person went alone and together during September. Bondan and Samantha play badminton every 4 and 5 days respectively and played together for the first time on August 7th. They are asked when they will play together again. The test questions involve calculating scores based on multiple choice answers and operations with fractions, exponents, and algebraic expressions.
