Similar Triangles and Figures, Enlargement Ratios & Proportions Geometry Word Problems

This geometry video tutorial provides a basic introduction on similar triangles and similar figures. It explains how to find the missing side using the proportions of similar triangles and even similar trapezoids. It explains how to solve for x as it relates to missing sides and missing angles. It discusses how to calculate the enlargement ratio and how to use it to determine the perimeter area of another triangle. This tutorial contains plenty of examples and practice problems.

My math teacher explaining this for a whole week, i understood it in 20 mins.

[jackwhatley]

watching this made it a lot easier to understand thx!

[abby-vque]

i cried in math class today because i had no idea what was going on, thank you for making these videos, whenever i have a hard time focusing on the lesson or the teacher doesn’t explain it fully in depth i know i can always just come search your youtube channel for whatever i need extra help with.

Every video you make made my teaching as a math tutor easier. <3 Thank you! God Bless, Stay safe.

MR. Organic Chemistry Tutor, thank you for another well-organized video/lecture on Similar Triangles, Ratios and Proportions in Plane/Analytic Geometry. This topic is very simple to follow, however the Proportions section of this lesson could be somewhat problematic. All students should pay close attention to similar triangles and their proportions.

I have no comment
but I noticed that every topic has nearly five videos that make me memorize the topic and even study them very well .thank you so much !!!! I appreciate every video you make even its not related to math. I feel every topic you put in this channel I will benefit from it in the future.
for real, God bless you!! and have a good day as you say!!!
it still no comment :P

This is way better than whatever my my math teacher thinks he's teaching. After watching this I realize it's either my teacher can't teach for shit or he's intentionally planning my failure.

I watch mostly all of your playlist and it is provoking and intriguing

Bro I have a retake on a math exam today, you are helping me so much bro, you help me with all my math. Thanks man, rlly appreciate it

[Yahonlyfoundmewithachiken]

Thank you man you making it seem so clear ❤

[IA._.A]

Thank you so much, this was very helpful, my teacher doesn't explain as good as you did

[crispybeans]

I’m listing to this whilst doing homework bro this helped a lot

[fikirteasrate]

[jazzyjavi]

Im so glad i found i have a test tomorrow
And i have no idea with this is

[kirianarose]

How do you know which number/ segment goes on top or bottom of the proportion?

[Adelaidexplorer]

Thank you sooo much brother keep it up

[NithishS-bizi]

The people who dislikes this video will be maths teachers😂...

[Coco-bcye]

I’m taking a test while watching this video

[unknownmuslimah]

So you start with the bigger triangle to do the ratio?
