Circle Theorems

QuestionAnswer
If a line is tangent to a circle then it is perpendicular to the radius drawn to the point of tangency
If a triangle is inscribed in a circle, and the hypotenuse is a diameter then the triangle is a right triangle
If a diameter of a circle is perpendicular to a chord then the diameter bisect the chord and its arc
If two chords intersect in the interior of a circle then the product of the links of the segments of one cord is equal to the products of the lengths of the segments of the other cord
A central angle is congruent to the arc inscribed between its end points
The measure of an inscribed angle is half the measure of its intercepted arc
A quadrilateral that is inscribed in a circle Has opposite angles that are supplementary
If a tangent and a cord intersect Then the measure of the angle is half the measure of the intercepted arc
If two segments from the same exterior point are tangent to a circle Then they are congruent
In a circle if two chords are equidistant from the center Then they are congruent chords
If a tangent and a secant intersect in the exterior of a circle Then the measure of the angle formed is half the difference of the measures of the intercepted arcs
If two tangents intersect in the exterior of a circle Then the measure of the angle formed is half the difference of the measures of the intercepted arcs
If two secants intersect in the exterior of a circle Then the measure of the angle formed is half the difference of the measures of the intercepted arcs

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
