#Circle Theorems: Your Ultimate Guide for the SAT Math 🎯

Hey there! Let's dive into the world of circles. These theorems are super important for the SAT, and once you get the hang of them, you'll be solving problems like a pro! This guide is designed to be your go-to resource the night before the exam. Let's make sure you're feeling confident and ready to ace it!

#Angles in Circles

#Central and Inscribed Angles

• Central Angle:

  • Formed by two radii meeting at the circle's center.
  • Its measure is equal to the measure of its intercepted arc. Think of it like a direct match! 📐

  

• Inscribed Angle:

  • Formed by two chords that meet on the circle's circumference.
  • Its measure is half the measure of its intercepted arc (or half the central angle that intercepts the same arc). It's like the central angle is sharing its measure. 🤓

  

• Inscribed Angle Theorem:

  • Inscribed angles that intercept the same arc are congruent (equal). If they're looking at the same slice of the pie, they're the same angle! 👯

• Angles in a Semicircle:

  • An angle inscribed in a semicircle is always a right angle (90 degrees). This is a classic setup on the test. 📐

#Special Angle Relationships

• Circumscribed Angle:
  • Formed by two tangent lines...
