Question
Find the area of the triangle ABC. Where AC=17cm,
AB=15cm, BC=8cmSolution
Hence Triangle ABC is a right-angled triangle. Therefore, a triangle that is inside a circle is right-angled, then the hypotenuse is the diameter of the circle. AB is height and BC base. Area of triangle ABC =1/2 × base × height. =1/2 ×8×15 =60cm2
