Angles, Triangles, and Transversal lines
Cards (6)
- One of the special properties of a triangle is that the sum of all three interior angles is always equal to 180 degrees
- Exterior angles - angles on the outside of the triangle
- Transversal line - a line that cuts through two parallel lines
- Corresponding angles - angles that are in the same position in relation to the transversal and therefore congruent
- Alternate exterior angles - angles on opposite sides of a transversal and outside the parallel line
- Alternate interior angles - angles that are on opposite sides of a transversal and inside the parallel line
