TANGENT LINES AND CIRCLES EXPLAINED!

Let's explore, identify, and describe the relationship between a circle and a tangent line and why the radius of a circle is perpendicular to the tangent where the radius intersects the circle.

Understand and apply theorems about circles.

Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.

What is a tangent line to a circle?
Why is a tagent line and a radius perpendicular?
How many times does a tangent line cross a circle?

So helpful to refresh my memory of math concepts! Breaks it down so that there is no misconceptions.

Better explained than the school system

Have been teaching elementary math skills forever; but diving back into middle school tutoring. You have eased my panic. Your intro/refresher on tangents relit my upper level brain, whew! Thank you so much, I will definitely be back.

Great explanation better than most pro teachers!!! 👍 Keep it up

[raghad]

You saved me! The explanation was so clear. Thank you so much!

I just got a 12 on my test so I watched this after and I completely get it now thank you

[aztecclient]

Thanks for making this video. Better than my math teacher's explanations

[karenreank]

It is really helpful and well explained for one to understand. Thank you

Oki sir! I love this explanation! Thank you sir! I was absent yesterday because of fever and the lesson was this! And now i get it!, it seems like i found another hidden treasure channel! I subscribed to you!

can i ask
How can i find the tangent segments when the central angle is given?please help me

[khaos_emeraldz]

School taught me this one time but this vid could teach me over and over

[saucesfc]

i’m just curious my school hasn’t taught this yet but is the 360 degrees permanent to all similar questions or just this one particularly?

edit: I rewatched the video and my questioned is answered

[juanitomendez]

My teacher complicated this so much thank you

[barirarazi]

Practice questions format is so helpful.

[veniceceneta]

Thanks for making this video. It helped me understand tangent theorem

[bunnyhead]

Thank you so much sir I will share this video to all my friends so they can learn also :)

I started thinking this in triangles and came up with X=(180-90-Y/2)x2, though this might have 2 or so more calculations, what do you know I got 59. It got easy when I hear what TAN line actually was (It was the 90 degreen angles). Our highschool math teacher, for long-math students, only taught us how to do it with a calculator. That guy wasn't really a people person, but he could fill the board without looking at the text book.

This video helped so much with my math HW 👍

Thanks for sharing. This is a good recall of facts
