Highlight the angle (s) that you already know. 2 State the alternate angle, co … WebSo we know that angle ABE must be congruent to angle CDE by alternate interior angles of a transversal intersecting parallel lines. Now, if we look at diagonal AC-- or we should call it transversal AC-- we can make the same argument. It intersects here and here. These two lines are parallel. So alternate interior angles must be congruent. heiko hafemann

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.
