Circle Theorems



This geometry video tutorial provides a basic introduction into circle theorems. It contains plenty of examples and practice problems.

Here is a list of topics:
1. If a radius is perpendicular to a chord, it bisects the chord into two congruent segments. The point of contact is the midpoint. Therefore, the radius becomes the perpendicular bisector of the chord.
2. Radius and diameter relationships in a circle
3. Circumference of a circle
4. Area of an circle
5. Congruent Chords Theorem – if two chords are equidistant from the center of a circle, then they are congruent.
6. Major Arcs, Minor Arcs, and Semicircles
7. Central angles and arc measures
8. Secant Lines and Tangent Lines
9. A tangent line is always perpendicular to the radius of the circle
10. Two tangent theorem
11. Tangent circles – internally tangent vs externally tangent
12. Common Tangents – common internal tangent vs common external tangent
13. Central angles and inscribed angles
14. Inscribed angles in circles & intercepted arcs
15. Tangent chord angles
16. Chord chord angles
17. Tangent tangent angles
18. Secant secant angles
19. Secant tangent angles
20. Congruent arcs theorem
21. Right angles, right triangles, diameter & semicircles
22. Quadrilaterals Inscribed In a Circle
23. Opposite angles of a quadrilateral inscribed in a circle are supplementary
24. Power Theorems
25. Chord chord power theorem
26. Tangent secant power theorem
27. Secant secant power theorem
28. Arc length of a circle
29. Area of a sector of a circle

  • 16:03 this cant be true because since the central angle acb and dce needs to have the same angle measure as the arc ab and de so ab cant equal to 100 degrees and de equals 60 degrees.

  • Its not a chord chord angle its a externally division of chord

  • God wins foreverrrr! I have the goal of having straight As and since I have all honors classes by God's grace! One of my classes was giving me trouble throughout the school year and my grade was an 89 but today God did it for me!!!!! my grade now is a 90 and I finally have straight As I tell you my God is real and in church, we have been talking about the undeserved grace of God. It was revealed to me when God said "My grace is sufficient for you, My power is made perfect in weakness " 2 Corinthians 12:9 It was was a faithful word to cling on! God is always with us even when we forsake Him so I want to testify to His good works! Also, my teacher gave me an 85 or so for a project but she lost the grade and when she asked me what it was, I didn't say anything, when I checked my grade she changed it to 100! I am telling you God truly wins when you give everything to Him! I even acquired varsity which is the top of athletics as a freshman I really cannot say all this was by my works or it was all God! May the Lord God be with us all and bless us all in the mighty name of Jesus Amen! and may we all go to heaven at the end and do His will for our lives in Jesus' mighty name Amen!!!!!!
