Important concepts to keep in mind
There are numerous aspects of the topic that you will need to understand before you begin solving the exercises of chapter 7 – triangles. These include the various formulas of similarity and the various types of triangles and the properties associated with them.
Types of triangles
| S. no | Types based on angles | Types based on size length |
| 1 | Acute – Each angle being less than 90o | Isosceles – Having two sides being of the same length |
| 2 | Isosceles – Having two sides of the same length | Right Isosceles – Being an isosceles with one 90o |
| 3 | Right- Having at least one angle at 90o | Equilateral – Having all sides being the same length |
- Similar triangles – Having the same angles but different side lengths; also known as equiangular triangles
- Congruent triangles – Having the same angles and the same length of each side
- Thales theorem/ Basic proportionality theorem: The ratio of each corresponding side of the similar triangles has the same ratio. For instance two similar triangles ABC and A’B’C’ will have identical values of: AB/A’B’ = BC/B’C’ = AC/A’C’
- Heron’s formula: Area = Square root of√s(s – a)(s – b)(s – c) where s is half the perimeter, or (a + b + c)/2
- Altitude: A line segment drawn from a vertex to the opposite side where it intersects perpendicularly
- Orthocentre: The point a which all the altitudes of a shape meet
- Median: Line segments drawn from a vertex to the midpoint of the opposite side
- Centroid: The meeting point of each median line
Additionally, it would be worthwhile to learn the formulas for the area of a triangle and the perimeter of each type of triangle.
For being rather early on there is a lot of content in this chapter and so there are plenty of questions in RS Aggarwal class 10 maths for you to become thorough with the concepts.
