FINAL GEOPARDY!
Name a pair of triangles that are congruent and name all postulates that justify this
conclusion.
ΔAMT =ΔHMT by SSS, SAS, or HL
Draw all possible common tangents of the two circles. Identify each tangent as
common internal tangent or a common external tangent.
Two common external tangents, one common internal tangent.
List the two important differences between a minor arc
and a major arc.
Minor arcs are less than 180° whereas major arcs are greater than 180°. Minor arcs are named with two points, major
arcs are named with three points.
Find the measure of the indicated arc. minor arc AB = _______ major arc BAD = _______
minor arc AC = _______ semicircle ABD = _______
major arc CDA = _______ major arc CDB = _______
50° 230°130° 180°230° 280°
Provide the general formulas used to calculate the measure of
an interior angle and the measure of an exterior angle.
Interior Angle = (arc + arc)/2 Exterior Angle = |arc – arc|/2
