As we know from the properties of this type of triangles, the height in it, which is drawn to its base, will also be the median.
Let’s determine what half of the base of our triangle will be equal to, when from the condition of the task we know that the length of the base is sixteen centimeters:
16: 2 = 8.
Let us determine what the height BD will be equal to, when from the condition of the task we know that the length of the side is seventeen centimeters:
