if you draw two right triangles using the line as the hypotenuse, do the triangles have to be similar? Why or why not?
diamong [38]

Answer:

All the right triangles will be similar.

Step-by-step explanation:

See the attached diagram.

Let us assume any two right triangles are drawn on the line OP, and AB and A'B' as the hypotenuse on the same line OP.

Since the slope of the line OP is constant and assume that it makes x° with the positive x-axis.

Hence, \tan x = \frac{AC}{BC} = \frac{A'C'}{B'C'}

⇒ \frac{AC}{A'C'} = \frac{BC}{B'C'}

Therefore, the sides of the two right triangles are in the same ratio and hence, Δ ABC and Δ A'B'C' are similar.

Hence, all the right triangles will be similar. (Answer)

Answer to A:

16.67%

Explanation to A:

If we need a number greater than five, the only number left is six, meaning there is \frac{1}{6}

\frac{1}{6} = 0.166666666

We can make it a percent by moving the decimal two places to the right and rounding to the thousandths place (two numbers). This would make our final answer 16.67%

Answer to B:

50%

Explanation to B:

There are three even numbers: 2, 4, and 6. This means we have a \frac{3}{6} chance to land on one.

\frac{3}{6} = 0.5

0.5 = 50%
