This mini-lesson introduces the definition and properties of triangles. You have instructor explain it to you in their voice and handwriting in the video with some examples that should help you for preparation in concepts and to improve study skills.
A triangle; one of the basic shapes of geometry, is a 3-sided polygon. Every triangle has three vertices and three sides which are line segments. E.g. A triangle with vertices A
is denoted ?ABC
. You will also learn here, with the help of examples and the solution, how to use the properties of and relationships among different types of triangles, to solve mathematical and real-world problems. For example, more commonly known properties are- in case of acute triangle (all angles are acute), equilateral triangle (all sides and angles are equal), isosceles triangle (two sides are equal), right triangle (one angle is right angle).
