Question

Triangle and its properties ncerr syllabus exercise 4

Answer 1

Answer:

Triangle is a two dimensional figure which is firmed by the intersection of three lines which is called it's edges ✓

$\blue{\bold{properties}} \:$

1) A triangle has three vertices it's fixed no triangle can have more then three vertices

2) A triangle has three edges and this is the fixed quantity no any triangle can have more then more three edges

3) Area of a equilateral triangle can be find by using the formula

$\huge{ \red{ \frac{ \sqrt{3} }{4} \times side \: ^{2} }}$

4) The area of an scalen triangle can be calculated out by using the heron formula

$\huge{ \red{area = \sqrt{s(s - a)(s - b)(s - c)} }}$

Here S is Semiperimeter which can be found by doing the sum of edges and then divide by 2 And a,b,and c are the edges of the triangle
