Page 2 Summary

This page continues with coordinate geometry problems and introduces systems of linear equations. The tasks involve finding coordinates of points and solving equations to determine unknown values. The problems require students to apply their knowledge of vector operations and algebraic manipulation. The page demonstrates how to set up and solve systems of equations to find the values of variables r and s.

Highlight: The problem-solving approach shifts from purely geometric calculations to algebraic methods, showing the interconnection between different areas of mathematics in Lambacher Schweizer Lösungen.

Page 1 Summary

This page focuses on geometric problems involving the Pythagorean theorem and coordinate geometry. The main task is to calculate lengths of sides and diagonals in a three-dimensional coordinate system. Students are required to use the distance formula derived from the Pythagorean theorem to solve these problems. The page also includes a question about comparing the lengths of diagonals in a rectangular solid.

Vocabulary: Pythagorean theorem - A fundamental principle in geometry stating that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of squares of the other two sides.

Example: The distance formula |AB| = √(4² + 3² + 2²) = √29 is used to calculate the length of a line segment in three-dimensional space.
