Given that line cd is a perpendicular bisector of triangle abc, if side ab has a length of 9 cm and side ac has a length of 16 cm, what is the length of side cd? answer to the nearest hundredth.

Sagot :

The length of the CD is 15.354 cm

As we know that a perpendicular bisector divides a line segment into 2 equal halves and makes a right angle with the line.

Here, the CD is the perpendicular bisector of AB.

Now from the above definition, we can classify that

AD = BD = 9/2 cm

= 4.5 cm

Also,

ΔACD is a right-angled triangle

According to the Pythagoras theorem for any right-angled triangle

length² + base² = hypotenuse²

In the given triangle,

length = CD

Base = AD

hypotenuse = AC

Hence we get

CD² + 4.5² = 16²

or, CD² + 20.25 = 256

or, CD² = 235.75

or, CD = √235.75

or, CD = 15.354
