Step-by-step explanation:
triangle is a polygon formed by any three non-collinear points on a plane having three sides and corresponding three angles. The sum of all angles in a triangle is equal to 180 degrees. In a triangle, the side opposite to the smallest angle is the shortest and the side opposite to the largest angle is the largest side.
If one angle of a triangle is a right angle, then the triangle is called a right triangle. The largest side of a right triangle is called the hypotenuse.
It is clear that the triangle is a right angled triangle.
Let AB=12 cm BC=5 cm and AC=13 cm
Now a perpendicular is drawn from A to AC.
