- Aangle D = 90°, square
- Bangle D = 100°, rectangle
- Cangle D = 90°, trapezium
- Dangle D = 80°, kite
Step-by-Step Solution
angle D = 360 - 270 = 90°. With four right angles and all sides equal, the shape is a square.
Answer: A) angle D = 90°, square
A quadrilateral ABCD has angle A = 90°, angle B = 90°, angle C = 90°.
