At least two pairs of consecutive angles are congruent in a _____.
-
- Parallelogram
- Isosceles trapezium
- Rhombus
- Kite
- Parallelogram
Correct Option: B
As per the given in question , we draw a figure cyclic trapezium ABCD
In an isosceles trapezium,
AB || CD ; AD = BC
AC = BD
The angles of base are equal. i.e.
∠A = ∠B ; ∠C = ∠D ; ∠A + ∠D = ∠B + ∠C = 180°
