How many 90 degrees arcs in a complete circle?
Any number from 4 to infinity, depending on whether the arcs are allowed to overlap
A tangent-tangent angle intercepts two arcs that measure 149 and 211 What is the measure of the tangent-tangent angle?
31 degrees
A tangent-tangent angle intercepts two arcs that measure 124 and 236 What is the measure of the tangent-tangent angle?
236-124/2=56 degrees
What is the arc of X in a circle whose degrees are 20 degrees 140 degrees and 50 degrees?
If the circumference is split into 4 arcs then the 4th arc is 360-20-140-50 = 150 degrees
Can two arcs have the same degree measure and still have different lengths?
s = rθs=arc lengthr=radius lengthθ= degree measure in radiansthis formula shows that arc length depends on both degree measure and the length of the radiustherefore, it is possible to for two arcs to have the same degree measure, but different radius lengthsthe circumference of a circle is a good example of an arc length of the whole circle

A circle is didvided into n congruent arcs. What is the measure of each arc if n equals 4?
It is: 360/4 = 90 degrees
A unit of measure used in measuring angles and arcs?
Degrees, Grads, or Radians.
Are arc measurements additive?
Yes, as long as the arcs do NOT overlap.
A tangent-tangent angle intercepts two arcs that measure 135 and 225 What is the measure of the tangent-tangent angle?
45 degrees
A tangent-tangent angle intercepts two arcs that measure 149 and 211 What is the measure of the tangent-tangent angle?
31 degrees
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
A tangent-tangent angle intercepts two arcs that measure 124 and 236 What is the measure of the tangent-tangent angle?
236-124/2=56 degrees
Are measures of minor arcs equal measures of inscribed angles?
No. The first is a measure of length, the second is a measure of angular displacement. If you have two circles with arcs of the same angular measure, the lengths of the arcs will not be the same.
Arcs of the same circle or congruent circles that have the same measure?
Congruent Arcs
Divide a circle into 5 parts?
The circumference of a circle is 360 degrees so measure out five 72 degree arcs and join them to the centre of the circle.
What is the measure of an angle formed by a tangent and a secant drawn to a circle from an external point if it intercepts arcs whose measures are 70 and 30?
20 degrees
