10.6 More Angle-Arc Theorems (Practice)

By AutenMath

A lesson on 1.) the relationship of inscribed and tangent-chord angles with the same or congruent arcs 2.) the measure of an inscribed angle whose intercepted arc is a semicircle and 3.) the relationship of tangent-tangent angles and their minor arcs

Students learn the definition of an inscribed angle, and that the measure of an inscribed angle is equal to ½ the measure of its intercepted arc. Students also learn the following theorems related to inscribed angles. If two inscribed angles intercept the same arc, then the angles are congruent. An angle inscribed in a semicircle is a right angle. If a quadrilateral is inscribed in a semicircle, then opposite angles are supplementary. The measure of an angle formed by a chord and its tangent is half the measure of the intercepted arc. Students are then asked to find the missing measures of arcs and angles in given circles using these theorems.

This lesson covers dividing integers. Students learn to divide integers using the following rules. A positive divided by a positive equals a positive. For example, +20 divided by +2 = +10. A positive divided by a negative equals a negative. For example, +20 divided by -2 = -10. A negative divided by a positive equals a negative. For example, -20 divided by +2 = -10. And a negative divided by a negative equals a positive. For example, -20 divided by -2 = +10. In other words, if the signs are the same, the quotient is positive, and if the signs are different, the quotient is negative. Note that any integer divided by zero is undefined. For example, +4 divided by 0 = undefined. And zero divided by any integer (other than zero) is zero. For example, 0 divided by +4 = 0.

This video explains what a radian is and how we determine the radian measure of an angle. The key point here is that the radian measure of an angle is the length of the arc (in radius lengths) cut off by that angle (if the angle's vertex is on the center of the circle). You may ask: Won't the size of the circle affect the radian measure of an angle? A key feature of circles is that they are all similar (and thus, proportional). When we account for their larger size, we take into account the larger radius. As a result, the radian measure is the same for all circles (since the radian measure is how many radius lengths long the arc is).

One of the most important properties we need to know about inscribed angles is that the measure of an inscribed angle is half the measure of the central angle that subtends the same arc. This video shows us the meaning of that property and proves that it is actually true. If nothing else, this video will help you get better acquainted with inscribed angles and how we measure them.
