True /False A) Area of triangle = 1/2 ×base ×height *
Answers
True
1/2×base×height is formula to find area of triangle.
Given : Area of triangular region = (1/2) * ( base) * height
To Find : true or false
Solution:
Area of a triangle = (1/2) * ( base) * height
Hence Given statement is correct
Correct answer is TRUE:
Triangle is a polygon having 3 sides.
Other formulas for Area of triangle
Taking ΔABC with sides AB =c , BC = a , AC = b and angles A , B and C
(1/2)abSinC
(1/2)acSinB
(1/2)bcSinA
(1/2)a² SInB SInC / SinA
(1/2)b² SInA SInC / SinB
(1/2)c² SInB SInA / SinC
Using Heron formuls
s = (a+ b + c)/2
Area = √s(s - a)(s - b)(s - c)
Area of triangle using coordinates of vertex
(a , b) , ( c , d) , ( e , f)
= (1/2) | a( d - f) + c( f - b) + e(b - d) |
For Equilateral triangle Area
= (√3 / 4) a² where a is the side
Area of triangular region = (1/2) * ( base) * height is TRUE
