How to Find the Missing Angle of the Triangle Step by Step ? | 2 Methods

In this lesson, we focused on calculating the missing angle in a triangle using two different methods. Firstly, we utilized trigonometric principles to reach the solution step by step. Trigonometry helped us understand the relationship between angles and sides, ensuring accurate results.
Secondly, we adopted a geometric approach. In this method, we used the fundamental properties of triangles and geometric rules to determine the missing angle. Geometric solutions provided a visual and conceptual understanding of the problem.
We thoroughly covered both methods and detailed the steps involved. By learning both approaches, you will gain the ability to tackle various problems from different perspectives.

Second method is very clever, Thank You

[@holyshit922]

After playing with sine and cosine law I got that
values of cosines are roots of following polynomial
(2t - 1)^2(4t^2 + 2t - 1)(8t^3 - 6t - 1)
but 0 < alpha < 45 degrees

At 1:05, GeoMathry has found, but not shown, that

New thumbnail? Nice 😊

[@geomathryy]

Thanks🙋‍♂️😅

@@geomathryy you're literally the best geometry channel

[@geomathryy]

Thank you so much🙋‍♂️

α=20...col teorema dei seni..BAC=100

[@harrymatabal8448]

If one angle is missing then there this figure cannot be a triangle 😂

Skipping too many steps made the video very hard to follow.
For example in 1:02 where did that sin3a come from?

[@geomathryy]

Since the angle BDC is 180 - 3 α , we have sin(180 - 3α) = sin 3α . I skipped some intermediate steps to keep the video short, but I answer any unclear steps in the comments.

@geomathryy
I know. I am a maths teacher. I think it's better to show steps that are not so obvious.
Skip only the obvious stuff.
