The vertex of this angle is at the center of the circle and the sides of the angle are chords.
What is a central angle?
This is the angle measure for a semi circle.
What is 180 degrees?
This type of arc has a degree measure less than 180 degrees.
What is a minor arc?
This is the distance along a circle that is part of the circumference.
What is arc length?
This is a "triangular" part of the circle where the vertex is the center of the circle.
What is a sector?
This line segment connects the center of the circle with a point on the circle.
What is a radius?
This is the sum of all the central angles in a circle.
What is 360 degrees?
Given: m<TME is 50 degrees.
This is m(arc TE)
What is 100 degrees?

What is circumference?
This is the area of half of circle G.
What is 39.3 sq. cm?
This line intersects a circle at exactly one point.
What is a tangent line?
This type of angle in a circle has a measurement that is equal to half the measurement of the intercepted arc.
What is an inscribed angle?
Given: m(arc TE) = 100 degrees
Given: m(arc OE) = 130 degrees
Given: m<RGE = 50 degrees
This is the m(arc MT).
What is 80 degrees?
This is the arc length of arc MTE.
What is 15.7 cm?

What is a circle?
This type of angle occurs at the intersection of a radius and tangent line to a circle.
What is a right or 90 degree angle?
The button is the innermost circle in a curling target. If the diameter of the button is 1 foot. This number rounded to the nearest hundred would be the circumference.
What is 3.14 feet?
Last August, Matt, the master gardener at Hollins Farm, noticed strange caterpillars munching on his Mutsu Crispin apples. One particularly hungry caterpillar munched a length of 5 centimeters around a 45 degree angle from the center of the apple. This number is the radius of the magnificent apple.
