Look at the GDZ solution. Does it use SSS (Side-Side-Side) or SAS (Side-Angle-Side)?
It’s always 180°. If your math says 181°, a triangle somewhere is crying. Look at the GDZ solution
Most points are lost because students forget to write down the "Дано" (Given) and "Найти" (To find) sections exactly as the KIM requires. 3. The Big Three Topics to Watch For If your math says 181°, a triangle somewhere is crying
Welcome to 7th grade, where we spend forty minutes proving that two triangles are identical just because they look like they are. If you’ve been scouring the internet for , you’ve probably realized that these tests are less about "doing math" and more about "legal arguments." 1. The "Axiom" Trap The Big Three Topics to Watch For Welcome
7th grade is where math stops being about numbers and starts being about "logic puzzles" involving lines and angles. Here’s a blog-style breakdown of how to use these materials without losing your mind.
In 6th grade, if a line looked straight, it was straight. In 7th grade KIMs, if you don't prove it’s straight using a specific theorem, it might as well be a wet noodle. This is why GDZ is so popular—not because students are lazy, but because the are incredibly picky. 2. How to use GDZ like a Pro (and not get caught) If you just copy the letters , your teacher will know. Use the answer keys as a roadmap :
Cover the answer and try to get to that same conclusion using the logic you just saw.
