Answer: BD = 9 units

Step-by-step explanation:

ABQ and CDQ are congruent triangles. That means their angle measures are the same but their lengths may be proportional.

19.2 / 32 = 0.6

15 * 0.6 = 9

So the length of side BD is 9 units.

When you are given three side lengths for a triangle, how do you know which length to substitute for a, b, or c in the Pythagore
Romashka [77]

Answer:

When Sum of square of two Sides is equal to square of third side of triangle.

Step-by-step explanation:

Given:

Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.

First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.

Hence the two side would according be a and b and third side will become c.

For example if length of triangle  is given as 6 cm, 8 cm and 10 cm.

We will first take square of all

6^2=36\\8^2=64\\10^2=100

Now we can see that

36+64=100\\6^2+8^2=10^2

Now by Pythagoras theorem.

a^2+b^2=c^2

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm
