Unit 3A: Line & Angle Relationships
Flashcards do conjunto (12)
- 1Triangle Sum Theoremthe sum in degrees of all the interior angles of a triangle is 180 degrees
- 2exterior angle of a polygonan angle outside the polygon formed by one of its sides and the extension of an adjacent side
- 3remote interior anglesinterior angles that are not adjacent to the exterior angle.
- 4Exterior Angle Theoremthe sum of the remote interior angles is equal to the measure of the exterior angle
- 5transversala line that intersects two or more lines
- 6Vertical anglesa pair of opposite congruent angles formed by intersecting lines
- 7corresponding anglesAngles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
- 8alternate interior anglesInterior angles that lie on opposite sides of the transversal. When the two lines are parallel then the alternate interior angles are congruent.
- 9alternate exterior anglesExterior angles that lie on opposite sides of the transversal. When the two lines are parallel then the Alternate Exterior Angles are congruent.
- 10same-side interior anglesTwo interior angles on the same side of the transversal. When the two lines are parallel then the sum of these angles is 180 degrees.
- 11same-side exterior anglesTwo exterior angles on the same side of the transversal. When the two lines are parallel then the sum of these angles is 180 degrees.
- 12Angle-Angle Similarity TheoremIf two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
