A right triangle is a triangle that has one right (90 degree) angle. A right-angled triangle (right triangle) is formed by perpendicular legs and a hypotenuse the longest edge. 15 units, 20 units The area of a triangle is the region or surface bounded by the shape of a Triangle. Let's first discuss right triangles in a general sense. The area of a triangle can be defined as the total space or region occupied by the three sides of any triangle. So, \(a = b = c\).So, \(s = \frac{ {a + b + c}}{2} = \frac{ {a + a + a}}{2} = \frac{ {3a}}{2}\)So, the area \( = \sqrt {s(s a)(s b)(s c)} = \sqrt {\frac{{3a}}{2} \times \left( {\frac{{3a}}{2} a} \right) \times \left( {\frac{{3a}}{2} a} \right) \times \left( {\frac{{3a}}{2} a} \right)} \)\( = \sqrt {\frac{{3a}}{2} \times \frac{a}{2} \times \frac{a}{2} \times \frac{a}{2}} = \sqrt {\frac{{3{a^4}}}{{16}}} = \frac{{\sqrt 3 }}{4}{a^2}\), where the length of the side of the triangle is \(a\).Hence, the Area of an Equilateral triangle is \( = \frac{{\sqrt 3 }}{4} \times {a^2} = \frac{{\sqrt 3 }}{4} \times {({\text{side}})^2}\), Let the two same sides of an isosceles triangle \(ABC\) be given by \(AB\) and \(AC\).
