Consecutive interior angles inside a triangle
WebIF the 80 is one of the base angles (across from one of the congruent sides), the other base angle is 80 and the third is 180- (80+80)=20 degrees for the vertex angle (between the two congruent sides). If 80 is the vertex angle, 80+x+x=180, subtract 80 and combine like terms to get 2x=100, divide by 2 to get each base angle is 50 degrees. WebWhen parallel lines get crossed by a transversal many angles are the same, as in this example: See Parallel Lines and Pairs of Angles to learn more. Vertically Opposite Angles Corresponding Angles Alternate Interior Angles Alternate Exterior Angles Consecutive Interior Angles Geometry Index
