True: in every isosceles trapezoid the base angles are equal to each other.
True
True OR False:
In all isosceles trapezoids the base Angles are equal.
The base angles are the two angles that touch the same parallel side (base). In an isosceles trapezoid, the angles touching the longer base are equal, and the angles touching the shorter base are also equal to each other.
No! Only the base angles are equal. The angles on the longer base are equal to each other, and the angles on the shorter base are equal to each other, but these two pairs have different measures.
Think of it this way: angles that sit on the same base (same parallel side) are equal. So if you have bases AB and CD, then angles A and B are equal, and angles C and D are equal.
No, but adjacent angles do! Each base angle plus the angle next to it (on the leg) equals 180°. This is because the legs are parallel to each other in an isosceles trapezoid.
No, only for isosceles trapezoids! Regular trapezoids don't have this property. The key is that isosceles trapezoids have equal legs, which creates the equal base angles.
