Given a right triangle. anglea is $51}^{\circ$ . A line is drawn from anglec $\left({90}^{\circ}\right)$ to the hypotenuse, creating a $7}^{\circ$ angle between the line and the cathetus adjusted to angleb. The cathetus adjusted to angel is 47cm. Find the length of the line drawn.

Can we find two non-congruent right triangles with whole-number lengths and congruent hypotenuses?

I have three random points, O, A, B, with these I can get angles $\alpha $ and $\beta $

How can I get the angle C, or better, directional vector of c which will be evenly in the middle, between the other two angles. Keep in mind that the angles might be of any value.

This old answer almost gets me were I need to be, but how can I change the final formula presented in the answer $g=\text{arctan}\phantom{\rule{thinmathspace}{0ex}}(2\mathrm{tan}r)$ to work with non-right triangles? to work with non-right triangles?

I have found lots of results searching for this, but they don't seem to work in my case.

It looks like a good solution, but I don't know enough about trig to determine the part to change in the final formula to make it not right triangle dependant

Determine whether the two triangles are similar.

Explain

1. The two triangles are not similar. Since$m\mathrm{\angle}B\ne m\mathrm{\angle}F$ , the triangles are not similar by the AA criterion.

2. The two triangles are similar. By the Interior angles theorom,$m\mathrm{\angle}C={67}^{\circ}$ , so the triangles are similar by the AA criterion.

3. The two triangles are similar. By the interior angles theorem,$m\mathrm{\angle}c={57}^{\circ}$ , so the triangles are similar by the AA similarity criterion.

3. The two triangles are not similar. By the interior angles theorem,$m\mathrm{\angle}C={57}^{\circ}$ so, the triangles are not similar by the AA similarity criterion.

Please give me a new answer and not a copied answer.

One of the largest issues in ancient mathematics was accuracy—nobody had calculators that went out ten decimal places, and accuracy generally got worse as the numbers got larger. The famous Eratosthenes experiment, that can be found at famousscientists,org/eratosthenes/, relied on the fact known to Thales and others that a beam of parallels cut by a transverse straight line determines an equal measure for the corresponding angles. Given two similar triangles, one with small measurements that can be accurately determined, and the other with large measurements, but at least one is known with accuracy, can the other two measurements be deduced? Explain and give an example.

The similarity of triangles gives rise to trigonometry.

How could we understand that the right triangles of trigonometry with a hypotenuse of measure 1 represent all possible right triangles? Ultimately, the similarity of triangles is the basis for proportions between sides of two triangles, and these proportions allow for the calculations of which we are speaking here. The similarity of triangles is the foundation of trigonometry.
