Question 2: The perimeter of a right-angled triangle is 32 cm. Its height and hypotenuse measure 10 cm and 13cm respectively. Find its area. WebA triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A triangle is usually referred to by its vertices. Hence, a triangle with vertices a, b, and c is typically denoted as Δabc.
