Area of a Triangle

Transcript

Area of a triangleLet us take right angled triangle ABC Let there be another triangle which is exactly same as ∆ABC If we join both these triangles We get a Rectangle ABCD Now, Area of Rectangle = Base × Height Area of ∆ABC + Area of ∆DCA = b × h Since both triangles are same, their area is same 2 Area of ∆ABC = b × h Area of ∆ABC = b × h Area of ∆ABC = 1/2 × b × h So, our formula is Area of triangle = 𝟏/𝟐 × Base × Height Now, it’s important to know what Base and Height of triangle are in different scenarios
