Question

What do you know about triangle BCD after you find this out in terms of trigonometry ratios for triangle BCD, what is The length of line cd insert text on the triangle to show the length of line cd

Answer 1

Given the triangle BCD

As shown BD is perpendicular to CD, there is a right angle at point D

So, the triangle BCD is a right angle triangle

The length of the line CD can be calculated using the Pythagorean theorem

As follows:

`CD^2=BC^2-BD^2`

Where BC is the hypotenuse of the triangle
