This document provides information about triangles in geometry, including:
- The basic elements of a triangle are its three vertices, three sides, and three interior angles.
- Triangles can be classified based on their sides as scalene (all sides unequal), isosceles (two sides equal), or equilateral (all sides equal). They can also be classified based on their angles as acute, obtuse, or right.
- The median, altitude, and angle bisector are described as secondary elements of a triangle. Properties of isosceles and equilateral triangles are presented, along with two criteria for triangle congruence based on sides and angles.
This document is a textbook on functions, derivatives, and integrals for high school mathematics in Greece (ΜΑΘΗΜΑΤΙΚΑ Γ ΛΥΚΕΙΟΥ). It contains 1,600 exercises on these topics across 23 chapters. The chapters cover concepts like the definition of a function, composition of functions, limits, continuity, derivatives, tangent lines, maxima and minima, integrals, and more. The exercises find domains of functions, evaluate functions, solve equations involving functions, and determine function formulas based on given properties. The textbook was edited by Nikos K. Raptis and aims to help students learn
